Solaris 11.4 Free For Open-Source Devs, Non-Production Use (phoronix.com) 51

Oracle has begun making a new version of Solaris 11.4 available for free/open-source developers and for non-production personal use. Phoronix reports: Solaris 11.4 CBE is the "Common Build Environment" and intended for open-source developers and strictly non-production personal use... That is if you want Solaris for new installs in 2022. The new Solaris 11.4 "CBE" spin is effectively a rolling release and from Oracle's perspective hopes to ease the integration of the open-source software relied upon by Solaris rather than being bound to the dated 11.4.0 GA release.

Downloading the new Solaris 11.4 CBE does require an Oracle account. The CBE builds are also described as "similar to a beta, they are pre-release builds of a particular SRU." The non-production use license is put out under the Oracle Technology Network Early Adopter License Agreement for Oracle Solaris. Oracle will allow upgrading from these free CBE releases to paid SRU releases under Oracle support contracts. More details for those interested in Oracle Solaris 11.4 CBE via the Oracle Solaris blog.

Wind Power Eclipses Both Coal, Nuclear In the US (npr.org) 87

An anonymous reader quotes a report from NPR: On March 29, wind turbines produced more electricity than coal and nuclear, the U.S. Energy Information Administration, an agency that collects energy statistics for the government, says. In the past, wind-powered electricity has gone beyond coal and nuclear on separate days, but this was the first time wind surpassed both on the same day. Natural gas is still the largest source of electricity generation in the country.

The EIA notes that in the spring and fall months, nuclear and coal generators reduce their output because demand tends to be lower, which could contribute to why wind turbines produced more electricity that day. But wind taking the No. 2 spot may be short-lived. The agency says electricity generation from wind on a monthly basis has been lower than natural gas, coal and nuclear generation. According to EIA projections, wind is not expected to surpass any other method in any month of 2022 or 2023.

How a Ukranian Soldier's Instagram Post Spawned the First New Pink Floyd Song in 28 Years (pinkfloyd.com) 60

"English rock band Pink Floyd has released new music for the first time in 28 years," reports UPI, "with proceeds from the track going to humanitarian relief in Ukraine amid its ongoing conflict with Russia."

"The single will be available on all streaming and download platforms..." the band said on their official web site. [Including downloads on Amazon Music and Apple Music]. "This is the first new original music that they have recorded together as a band since 1994's The Division Bell." The track sees David Gilmour and Nick Mason joined by long-time Pink Floyd bass player Guy Pratt and Nitin Sawhney on keyboards and features an extraordinary vocal performance by Andriy Khlyvnyuk of Ukrainian band Boombox.... David, who has a Ukrainian daughter-in-law and grandchildren says: "We, like so many, have been feeling the fury and the frustration of this vile act of an independent, peaceful democratic country being invaded and having its people murdered by one of the world's major powers...."

"Recently I read that Andriy had left his American tour with Boombox, had gone back to Ukraine, and joined up with the Territorial Defense. Then I saw this incredible video on Instagram, where he stands in a square in Kyiv with this beautiful gold-domed church and sings in the silence of a city with no traffic or background noise because of the war. It was a powerful moment that made me want to put it to music." While writing the music for the track, David managed to speak with Andriy from his hospital bed in Kyiv where he was recovering from a mortar shrapnel injury. "I played him a little bit of the song down the phone line and he gave me his blessing...."

Speaking about the track David says, "I hope it will receive wide support and publicity. We want to raise funds for humanitarian charities and raise morale. We want to express our support for Ukraine and, in that way, show that most of the world thinks that it is totally wrong for a superpower to invade the independent democratic country that Ukraine has become".

All proceeds will go towards Ukrainian humanitarian relief.

On March 11 the band had posted another update on their official site: To stand with the world in strongly condemning Russia's invasion of Ukraine, the works of Pink Floyd, from 1987 onwards, and all of David Gilmour's solo recordings are being removed from all digital music providers in Russia and Belarus....

San Francisco Leads the Nation In No One Wanting To Work In an Office (sfgate.com) 143

An anonymous reader quotes a report from SFGate: Bad news for anyone hoping that Bay Area workers return to the office for good: San Francisco leads the nation in how many days employees want to work from home. According to a recent survey co-conducted by Stanford economics professor Nicholas Bloom, workers want to cut how many days they spend in the office by more than 53%, a nation-leading number. That's 4 percentage points more than New York and 6 percentage points more than Los Angeles.

San Francisco also ranks third -- behind New York City and Los Angeles -- in how much less they intend to spend in the city while they are in the office. According to a slide deck provided by Bloom to SFGATE, the average San Francisco office worker will spend an average of $5,293 less per year compared with before the COVID-19 pandemic. He first presented these findings at a conference at New York's Federal Reserve Bank, as first reported by Bloomberg.
"Employers value working from home -- they really like it, as it's a huge hiring and retention policy," Bloom said. "Why wouldn't you do something that makes them more productive and happier?"

Bloom went on to say that "tech workers, on average, value working from home two to three days a week as much as an 11% pay increase," reports SFGate.

Astrophotographer Spots Spacewalking Astronauts From the Ground (space.com) 35

InfiniteZero shares a report from Space.com: Last Wednesday (March 23), NASA astronaut Raja Chari and the European Space Agency's Matthias Maurer spent nearly seven hours outside the International Space Station, performing a variety of maintenance work. Amazingly, astrophotographer Sebastian Voltmer managed to capture a snapshot of the spacewalk action from the ground -- and from Maurer's hometown of Sankt Wendel, Germany, no less. "I feel like I just made a once-in-a-lifetime image," Voltmer wrote at SpaceWeather.com, which featured the photo in its online gallery.

Google Proposes Shutdown Changes To Speed Linux Reboots (phoronix.com) 50

UnknowingFool writes: Google has proposed a change on how Linux kernel handles shutdowns specifically when NVMe drives are used. The issue that Google is finding is that the current NVMe drivers use synchronous APIs when shutting down and it can take 4.5 seconds for each NVMe drive. For a system with 16 NVMe drives that could take more than a minute longer. While this is a problem that only large enterprise systems face currently, more enterprises are replacing their mechanical disk RAID servers with SSD ones.

[...] The proposed patches from Google allow for an optional asynchronous shutdown interface at the bus level. The new interface maintains backwards compatibility with the synchronous implementation. As part of the patches, all PCI Express based devices are moved to use the async interface, implements the changes at the PCIe level, and then the changes to the NVMe driver to exploit the async shutdown interface.

Russian Troops' Tendency to Talk on Unsecured Lines is Proving Costly (sfgate.com) 263

The Washington Post reports Russian troops in Ukraine "have relied, with surprising frequency, on unsecured communication devices such as smartphones and push-to-talk radios."

But this is leaving Russia's units "vulnerable to targeting...further underscoring the command-and-control deficiencies that have come to define Moscow's month-long invasion, observers say." The Russian military possesses modern equipment capable of secure transmission, but troops on the battlefield have reached for simpler-to-use but less-secure lines because of uneven discipline across the ranks, an apparent lack of planning for conducting a sustained fight over long distances, and Russian attacks on Ukraine's communication infrastructure that it, too, has relied on, experts say.

A European intelligence official, speaking on the condition of anonymity to discuss NATO's battlefield assessments, said that since the invasion began in late-February, there have been multiple instances of Russian commanders confiscating their subordinates' personal phones for fear they would unwittingly give away a unit's location.... There is evidence that the United States and other NATO countries have provided Ukrainian forces with electronic warfare equipment capable of interrupting Russian transmissions and allowing them to target Russian command posts, said Kostas Tigkos, a Russian military expert at the defense analysis firm Janes Group. By destroying Russia's communication nodes, the Ukrainians could pressure their adversaries to use less-secure equipment, he said, increasing the likelihood their conversations will be intercepted or their positions triangulated....

There is anecdotal evidence that Russia's unsecured communications have led to battlefield losses. One Russian general was purportedly killed in an airstrike after his cellphone was detected by the Ukrainians, the New York Times reported earlier this month.

The Post reports that Russian military transmissions over unsecured lines are now even being listened to by amateur radio enthusiasts at online sites like WebSDR (a software-defined radio receiver connected to the internet).

"Don't say the last names on air!" one Russian service member was apparently overheard saying by Shadow Break International, a U.K.-based open-source intelligence consultancy.

What Andy Warhol Was Really Thinking on Commodore's Amiga Demo Day (ourboard.org) 11

Long-time Slashdot reader theodp writes: Thirty five years after Andy Warhol's death, the NY Times reports on a new wave of Warhol-Mania as the famed pop artist is currently the subject of a Netflix documentary series (The Andy Warhol Diaries), an exhibition at the Brooklyn Museum and multiple theatrical works. The documentary revisits the 1985 launch of the Commodore Amiga, where Warhol demonstrated the Amiga's then-unparalleled graphical power by 'painting' Blondie lead singer Debbie Harry's portrait. Even as the flood-filling goes bad, Warhol does his best to put on a brave public face ("This is kind of pretty. Oh, it's beautiful."), but reveals his true thoughts in his demo day diary entry.

"The day started off with dread as I woke up from my dreams and thought about my live appearance for Commodore computers," Warhol recalls in the documentary (in an AI-generated voice). "And how nothing is worth all this worrying, to wake up and feel so terrified. Commodore wants me to be a spokesman. It's a $3,000 machine that's like the Apple thing, but can do 100 times more. The whole day was spent being nervous and telling myself that if I could just get good at stuff like this, then I could make money that way, and I wouldn't have to paint. The drawing came out terrible. And I called it a masterpiece. It was a real mess.

"I said I wanted to be Walt Disney and that if I'd had this machine ten years ago, I could have made it."

Five NFT versions of Warhol's recovered Amiga artwork were sold for $3,377,500 last May to benefit the Andy Warhol Foundation.

Russians Are Racing To Download Wikipedia Before It Gets Banned (slate.com) 61

An anonymous reader quotes a report from Slate.com: On March 1, after a week of horror in Ukraine, reports came out that Russia's censorship office had threatened to block Russian Wikipedia. A 32-year-old who asked to be called Alexander soon made a plan to download a local copy of Russian-language Wikipedia to keep with him in eastern Russia. "I did it just in case," he told me over Instagram Messenger before sharing that he and his wife are "working on moving to another country" with their two dogs, Prime and Shaggy. (Instagram has been blocked in Russia, but many continue to access it using virtual private networks. On Monday, the Russian government officially declared Facebook and Instagram "extremist organizations.")

Alexander wasn't the only Russian citizen to make a local copy of Wikipedia. Data suggests that after the threats of censorship, Russians started torrenting Wikipedia in droves. Currently, Russia is the country with the most Wikipedia downloads—by a landslide. Before the invasion, it rarely broke the top 10, but after the Feb. 24 invasion of Ukraine, it has kept a solid hold on first place. The 29-gigabyte file that contains a downloadable Russian-language Wikipedia was downloaded a whopping 105,889 times during the first half of March, which is a more than 4,000 percent increase compared with the first half of January. According to Stephane Coillet-Matillon, who leads Kiwix, the organization that facilitates these downloads, Russian downloads now constitute 42 percent of all traffic on Kiwix servers, up from just 2 percent in 2021. "We had something similar back in 2017 when Turkey blocked Wikipedia," he said, "but this one is just another dimension."
"Wikipedia routinely makes a dump of its databases available publicly, which Kiwix compresses into an archive so it can be more easily shared," adds Slate. "The entirety of English Wikipedia, from 'List of Informally Named Dinosaurs' to 'Floor' to 'Skunks as Pets' and everything in between, is 87 GB with pictures or 47 GB without. Russian-language Wikipedia is even smaller, continuing 1.8 million articles compared with English Wikipedia's 6.4 million."

Linux Random Number Generator Sees Major Improvements (phoronix.com) 80

An anonymous Slashdot reader summarizes some important news from the web page of Jason Donenfeld (creator of the open-source VPN protocol WireGuard): The Linux kernel's random number generator has seen its first set of major improvements in over a decade, improving everything from the cryptography to the interface used. Not only does it finally retire SHA-1 in favor of BLAKE2s [in Linux kernel 5.17], but it also at long last unites '/dev/random' and '/dev/urandom' [in the upcoming Linux kernel 5.18], finally ending years of Slashdot banter and debate:

The most significant outward-facing change is that /dev/random and /dev/urandom are now exactly the same thing, with no differences between them at all, thanks to their unification in random: block in /dev/urandom. This removes a significant age-old crypto footgun, already accomplished by other operating systems eons ago. [...] The upshot is that every Internet message board disagreement on /dev/random versus /dev/urandom has now been resolved by making everybody simultaneously right! Now, for the first time, these are both the right choice to make, in addition to getrandom(0); they all return the same bytes with the same semantics. There are only right choices.

Phoronix adds: One exciting change to also note is the getrandom() system call may be a hell of a lot faster with the new kernel. The getrandom() call for obtaining random bytes is yielding much faster performance with the latest code in development. Intel's kernel test robot is seeing an 8450% improvement with the stress-ng getrandom() benchmark. Yes, an 8450% improvement.

Hundreds of GoDaddy-Hosted Sites Backdoored In a Single Day (bleepingcomputer.com) 19

Internet security analysts have spotted a spike in backdoor infections on WordPress websites hosted on GoDaddy's Managed WordPress service, all featuring an identical backdoor payload. The case affects internet service resellers such as MediaTemple, tsoHost, 123Reg, Domain Factory, Heart Internet, and Host Europe Managed WordPress. BleepingComputer reports: The discovery comes from Wordfence, whose team first observed the malicious activity on March 11, 2022, with 298 websites infected by the backdoor within 24 hours, 281 of which were hosted on GoDaddy. The backdoor infecting all sites is a 2015 Google search SEO-poisoning tool implanted on the wp-config.php to fetch spam link templates from the C2 that are used to inject malicious pages into search results. The campaign uses predominately pharmaceutical spam templates, served to visitors of the compromised websites instead of the actual content.

The goal of these templates is likely to entice the victims to make purchases of fake products, losing money and payment details to the threat actors. Additionally, the actors can harm a website's reputation by altering its content and making the breach evident, but this doesn't seem to be the actors' aim at this time. The intrusion vector hasn't been determined, so while this looks suspiciously close to a supply chain attack, it hasn't been confirmed. [...] In any case, if your website is hosted on GoDaddy's Managed WordPress platform, make sure to scan your wp-config.php file to locate potential backdoor injections. Wordfence also reminds admins that while removing the backdoor should be the first step, removing spam search engine results should also be a priority.

Four US States Plan $8 Billion Hydrogen Fuel Hub (apnews.com) 145

This week the governors of Colorado, New Mexico, Utah and Wyoming announced plans for a "hydrogen hub," reports the Associated Press.

The states hope to use $8 billion in recently approved federal infrastructure funding to make hydrogen — the most abundant element in the universe — "more available and useful as clean-burning fuel for cars, trucks and trains." Hydrogen can be derived from water using an electric current and when burned emits only water vapor as a byproduct. The fuel could theoretically reduce greenhouse emissions and air pollution, depending on how it's obtained. As with electric vehicles, however, hydrogen's potential has been limited by infrastructure. Lack of fueling stations limits the market for hydrogen-fueled vehicles. Few hydrogen-fueled vehicles limits investment in producing and moving hydrogen....

Critics point out that as it's now produced, hydrogen isn't green, carbon-free or unlimited. Currently nearly all hydrogen commercially produced in the U.S. comes not from water but natural gas, according to the U.S. Energy Information Administration. While advocates say using fossil fuels to produce hydrogen now can help to develop a clean industry later, environmentalists are skeptical. "It's essentially a push for expanded oil and gas development. More oil and gas development is completely at odds with the need to confront the climate crisis and drastically reduce our dependence on fossil fuels," Jeremy Nichols with the Santa Fe, New Mexico-based environmental group WildEarth Guardians said by email.

Colorado, New Mexico and Wyoming rank seventh, eighth and ninth, respectively, for U.S. onshore gas production. Utah also is significant gas-producing state, according to the Energy Information Administration.

'Windowless Bunker': First Reviews Come In for Disney's $5,000 'Star Wars Hotel (sfgate.com) 74

Disney World's "Star Wars: Galactic Starcruiser" hotel will be expensive and immersive, writes SFGate. ("For two adults, the starting price is about $5,000. For three adults and one child, it's nearly $6,000.")

And while the hotel doesn't open to paid guests until Tuesday, free previews have already been given to online influencers: Reviews so far are generally positive — particularly praised are the character actors who carry the experience — with a few caveats. Because the hotel itself, called the Halcyon, is supposed to be a luxury cruise ship in space, the biggest complaint is that rooms are small and cramped...

For some, the lack of windows may add to a sense of claustrophobia. Hotel rooms have a digital display showing outer space and no view of the real outside world. Folks needing some fresh air can, however, visit an outdoor communal space called a "climate simulator." Reporters from the YouTube channel Disney Food Blog, which has nearly 800,000 subscribers, were invited to the media preview. In their review of the hotel, they put it thusly: "Disney went all-in on an experience that seemingly puts only the wealthiest guests inside a windowless bunker for two full days."

But most reviewers agreed that guests will be spending minimal time in their room anyway. The two days are packed with lightsaber training, clandestine rendezvous, elaborate entertainment and exploration of the ship. Guests need to download an app for their smartphone to chat with characters on board, receive their missions and learn their storylines. This was the other major drawback: If you're an introvert, this may be the wrong trip for you.

Largest Plane Ever Built May Have Been Destroyed, Ukraine Foreign Minister Says (sfgate.com) 152

SFGate reports: The largest plane ever built has been destroyed at an airport outside Kyiv, Ukraine Minister of Foreign Affairs Dmytro Kuleba said Sunday....

The Antonov An-225 Mriya was built in Ukraine in 1985 when the nation was still controlled by the Soviet Union. It has six turbofan engines and is the heaviest aircraft ever built. It was created as a strategic airlift cargo craft, carrying Soviet space orbiters, but was later purchased by Antonov Airlines. It's since been used to airlift oversized cargo and large loads of emergency aid during natural disasters....

Although Kuleba's tweet confirmed the plane's demise, Antonov says it is still gathering information on the massive plane's fate.

Is There Hope in New Climate Science? (msn.com) 69

Three climate scientists wrote an encouraging opinion piece for the Washington Post: One of the biggest obstacles to avoiding global climate breakdown is that so many people think there's nothing we can do about it. They point out that record-breaking heat waves, fires and storms are already devastating communities and economies throughout the world. And they've long been told that temperatures will keep rising for decades to come, no matter how many solar panels replace oil derricks or how many meat-eaters go vegetarian. No wonder they think we're doomed.

But climate science actually doesn't say this. To the contrary, the best climate science you've probably never heard of suggests that humanity can still limit the damage to a fraction of the worst projections if — and, we admit, this is a big if — governments, businesses and all of us take strong action starting now.

For many years, the scientific rule of thumb was that a sizable amount of temperature rise was locked into the Earth's climate system. Scientists believed — and told policymakers and journalists, who in turn told the public — that even if humanity hypothetically halted all heat-trapping emissions overnight, carbon dioxide's long lifetime in the atmosphere, combined with the sluggish thermal properties of the oceans, would nevertheless keep global temperatures rising for 30 to 40 more years. Since shifting to a zero-carbon global economy would take at least a decade or two, temperatures were bound to keep rising for at least another half-century.

But guided by subsequent research, scientists dramatically revised that lag time estimate down to as little as three to five years. That is an enormous difference that carries paradigm-shifting and broadly hopeful implications for how people, especially young people, think and feel about the climate emergency and how societies can respond to it.

This revised science means that if humanity slashes emissions to zero, global temperatures will stop rising almost immediately. To be clear, this is not a get-out-of-jail-free card. Global temperatures will not fall if emissions go to zero, so the planet's ice will keep melting and sea levels will keep rising. But global temperatures will stop their relentless climb, buying humanity time to devise ways to deal with such unavoidable impacts.

In short, we are not irrevocably doomed — or at least we don't have to be, if we take bold, rapid action.

ReiserFS Proposed To Be Removed From Linux In 2022 (phoronix.com) 217

UnknowingFool writes: Linux kernel developers have discussed on the kernel developers forum to remove ReiserFS from the kernel starting in 2022. ReiserFS was added as Linux's first journaling file system 21 years ago with SUSE using it as the default filesystem until 2006. However, since Hans Reiser was sent to jail 15 years ago for murder, there has not been much development or interest in it. Noting that there have been no user-spotted fixes since 2019, longtime kernel developer Matthew Wilcox also cited that ReiserFS was only block for some kernel changes he wished to implement. These days there are better alternatives like EXT4, Btrfs, XFS, and OpenZFS.

After Blackouts, Texas Became a Top State for New Solar Installations as Thousands Install Microgrids (houstonchronicle.com) 60

"Thousands of Texans who have turned to solar power and battery storage, creating so-called microgrids, as a solution to blackouts," reports the Houston Chronicle.

"With a venture creating the same little power plants for apartment buildings, Texas has become a national leader in residential solar power installations." From 2019 to 2020, small-scale solar capacity in Texas grew by 63 percent, to 1,093 megawatts from 670 megawatts, according to the Energy Information Administration. In the first three quarters of 2021, another 250 megawatts of residential solar were installed in the state, according to the Solar Energy Industries Association. In last year's third quarter alone, Texas ranked second behind California in the amount of power from new installations during the period, the industry's Washington, D.C. trade group said.

Surging demand for residential solar power in Texas after the February 2021 freeze put pressure on installers to keep up, said Abigail Hopper, president and CEO of the association. The race to buy new rooftop panels has slowed some, she said, but Texas remains among the top three states for new installations. And the shrinking price of solar cells will help support its growing popularity, Hopper said.

"I think as more and more Americans really struggle with the impact of severe weather — everything from fires, the cold, hurricanes, droughts — and see the impacts on power and power outages, you're going to continue to see folks looking for resiliency," Hopper said.

San Francisco's Mayor is Urging Employers to Return Workers to Downtown Offices (sfchronicle.com) 288

San Francisco mayor London Breed "is working with business leaders to push San Francisco employers to start bringing more workers back to downtown offices at some point in March," reports the San Francisco Chronicle.

"Breed said she was developing a strategy with the Chamber of Commerce and other groups to help turn around the city's once-bustling commercial core." San Francisco's downtown has been hit hard as most employees have stayed home during the pandemic.... Breed's comments reflect the pressure she's under to revive San Francisco's struggling downtown where weekday foot traffic remains sparse, small businesses have shuttered and massive office towers sit largely empty nearly two years after COVID-19 sent most workers home indefinitely. Some workers are likely to stay remote because they're concerned about being exposed to the virus or for other personal reasons.... San Francisco officials predict that around 15% of office workers will stay remote when the economy is expected to stabilize in 2023, a major shift that would permanently hurt business tax revenue, according to a report released last month....

Despite rampant commercial vacancies and an abundance of employees choosing to work remotely in perpetuity or leave San Francisco entirely, Breed said she was encouraged by a number of businesses that have signed new leases or are looking at new opportunities in the city. "Working from home has been so convenient and so comfortable, let's be honest," Breed said. "But at the same time, people miss people. They miss being out in the streets. They miss being at places and restaurants."

John Bryant, CEO of the Building Owners and Managers Association of San Francisco, tells the newspaper that downtown San Francisco's buildings are only about 20% occupied now. And that this year he hopes to see that double — to 40%.

The Sun Has Erupted Non-Stop All Month, and There Are More Giant Flares Coming (sciencealert.com) 68

Over the past few weeks the sun "has undergone a series of giant eruptions that have sent plasma hurtling through space," reports Science Alert: Perhaps the most dramatic was a powerful coronal mass ejection and solar flare that erupted from the far side of the Sun on February 15 just before midnight. Based on the size, it's possible that the eruption was in the most powerful category of which our Sun is capable: an X-class flare.

Because the flare and CME were directed away from Earth, we're unlikely to see any of the effects associated with a geomagnetic storm, which occurs when material from the eruption slams into Earth's atmosphere. These include interruptions to communications, power grid fluctuations, and auroras. But the escalating activity suggests that we may anticipate such storms in the imminent future. "This is only the second farside active region of this size since September 2017," astronomer Junwei Zhao of Stanford University's helioseismology group told SpaceWeather. "If this region remains huge as it rotates to the Earth-facing side of the Sun, it could give us some exciting flares."

According to SpaceWeatherLive, which tracks solar activity, the Sun has erupted every day for the month of February, with some days featuring multiple flares. That includes three of the second-most powerful flare category, M-class flares: an M1.4 on February 12; an M1 on February 14; and an M1.3 on February 15. There were also five M-class flares in January. The mild geomagnetic storm that knocked 40 newly launched Starlink satellites from low-Earth orbit followed an M-class flare that took place on January 29.

The article suggests this is normal activity, since the sun is about halfway towards "solar maximum" (its peak of sunspot and flare activity) expected to arrive in 2025, while the "solar minimum" was in 2019.

Further Reading: SciTechDaily reports that the ESA/NASA Solar Orbiter spacecraft has now "captured the largest solar prominence eruption ever observed in a single image together with the full solar disc."
