#Solarflares may show predictable warning signs hours before erupting
Observations could help forecast big outbursts in the future
Observations of the lead-up to a massive #solarflare revealed changes near #sun's surface starting three hours before the flash, scientists report. The results could help experts develop methods to predict future solar flares, potentially giving us time to protect Earth’s power grid, orbiting satellites and astronauts.

Near X-Flare
June 23, 2024 @ 14:50 UTC
"Is our old pal #AR3664 (3697 and now 3723) still active?"Of course it is. A near #XFlare (M9.3) was detected at 13:01 UTC (Jun 23). The flare itself was fairly rapid, so a coronal mass ejection (CME) is likely not associated. We will get a better at the returning flare champion over the next few days.
"Now back for the third time, AR 3664 (3697) is returning into view from off the farside of the Sun. This region was first assigned 3664 on May 1st and would go on to produce non stop X-Flares and the resulting eruptions were responsible for the extreme #geomagnetic storm on May 10-11. It would reappear again on May 28th and was reassigned AR 3697 and would produce additional major solar flares. What will it have in store for us this time around? Stay tuned to find out."

#XFlares Are Piling Up
June 1, 2024 @ 10:20 UTC"Good morning. How about another X-Flare!
"The latest event measuring X1.4 was just detected around AR 3697 (3664) at 08:48 UTC (Jun 1). Much like the X-Flare yesterday evening, a CME does not appear to be associated with this event. Some dimming was observed to the north of 3697 before this event, but coronagraph imagery does not seem to reveal any plasma leaving the Sun. The flare producing machine is now in a good location for potential Earth directed eruptions.
"And with this now being the 49th X-Flare of the current solar cycle, we have tied the X-Flare total from the previous solar cycle 24. When will #50 take place? Stay tuned to find out."

#SpaceWeather update via #SolarHam
"So is old region #AR3664 still active? Of course it is!
"An X2.9 solar flare was observed around the returning region at 07:08 UTC (May 27, 2024). The event is also responsible for an energetic coronal mass ejection (#CME) now emerging in updated coronagraph imagery. Because the sunspot region is still located behind the east limb, the flare itself was likely stronger than the X2.9 measurement. The CME itself should be directed away from our planet. We may see some busy days ahead of us. Stay tuned!"

Estimated X12 #SolarFlare from [presumed] #AR3664, which is on the far side of the Sun right now.
#CarringtonEvent was believed to be X45.
#AR3664 will be Earth-facing again soon.
"A fast moving, full halo coronal mass ejection (CME) is seen leaving the Sun this morning beginning around 05:30 UTC (May 20). Based on updated imagery, this event occurred on the farside of the Sun and is not Earth directed. Perhaps our old friend AR 3664 is up to its old tricks again. We should begin to see the big sunspot region turn back into view early next week."

[May be behind a paywall] The Strongest #SolarStorm in 20 Years Did Little Damage, but Worse #SpaceWeather Is Coming
Years of careful planning helped safeguard against last weekend’s severe space weather, but we still don’t know how we’d cope with a monster event
By Jonathan O'Callaghan & Lee Billings
May 16, 2024"For years, we have been warned about impending doom from the sun. If pointed in our direction, powerful eruptions of radiation and plasma from our star can strike our planet to supercharge Earth’s atmosphere and magnetic field, effectively hitting a global 'reset' button on much of our #ModernTechnology. A sufficiently intense bombardment could raise a #Geomagneticstorm that would push satellites out of orbit, short out submarine cables that suture together the #Internet and plunge the world into darkness with massive #blackouts from collapsed #PowerGrids. Yet this past weekend, when one of the strongest solar outbursts in 20 years blasted our planet, we managed to emerge unscathed thanks to years of careful public and private planning.
"The storm has ebbed, although the solar region that sparked it has since spat out additional monstrous flares—fortunately no longer targeted at Earth because of the sun’s spin [which will change in a short time, as that spot will once again be Earth-facing]. But while we’ve passed our biggest test yet, experts say now is not the time to let down our guard: the question of more cataclysmic solar activity isn’t a matter of 'if' but 'when.'
"'This is a success story,' says Shawn Dahl, a space weather forecaster at the National Oceanic and Atmospheric Administration’s [#NOAA] Space Weather Prediction Center (#SWPC) in Boulder, Colo., but the weekend’s storm was 'nowhere close' to the strength of more powerful known historical events. Is it time to put our feet up? 'Heck no,' he says.
"On May 8, after ground- and space-based telescopes detected multiple explosive outbursts from the sun headed for Earth, the SWPC issued a warning of an imminent severe space weather event. At least seven of these outbursts, known as coronal mass ejections, or #CMEs, walloped our planet with billions of tons of solar plasma—an interplanetary punch that left Earth’s magnetic field ringing and made the upper atmosphere swell, almost as if bruised. The resulting geomagnetic storm was the most severe since 2003. It posed potentially grave dangers to global infrastructure while also bathing much of the world in achingly beautiful #auroral displays.
"At present, it’s difficult to say just how close we came to catastrophe because many companies— from grid controllers to satellite operators—do not like to reveal information on how a geomagnetic storm affected them, says Daniel Welling, a climate and space scientist at the University of Michigan. "'They don’t want to look like they’re vulnerable,' he says. 'Satellite operators have to insure their spacecraft, and that can be very expensive.' Yet various scattered reports are already offering some insight into the storm’s disruptive effects. Flight trackers showed airlines rerouting planes to avoid Earth’s poles, where crews and passengers would have been exposed to worrisome spikes in #CosmicRadiation from the storm. Transpower, New Zealand’s state-owned enterprise running that nation’s electric power, said in a statement that it had preemptively 'switched off some circuits across the country on Saturday [May 11],' and as a result, there was 'no impact on New Zealand’s electricity supply.' In Minnesota, the firm Minnesota Power opened capacitor banks to deal with possible effects from the storm. Similar precautions were likely taken at other power grids around the world, too, although the lack of information makes it 'tremendously' difficult to know how effective those measures were, Welling says.
"Geomagnetic storms can also play havoc with signals from #GPS satellites, and multiple farmers reported issues with GPS-guided farming equipment over the weekend. In South Dakota, one farmer’s tractor started #DrivingInCircles during the storm, and multiple farmers reported outages on social media. 'Our GPS on both the planter and the strip tiller were absolutely bonkers today,' one commenter wrote on Reddit. 'I saw this post and looked ... no GPS,' said another. LandMark Implement, a John Deere dealership based in Nebraska and Kansas, texted its customers an advisory to 'turn off' GPS devices on their farming equipment. 'The base stations were sending out corrections that have been affected by the geomagnetic storm and were causing drastic shifts in the field,' the company noted in an online post. LandMark declined to comment further when contacted.
"The storm posed hazards in space as well. Seven astronauts on the International Space Station were mostly safe from the storm’s effects, #NASA said, but did have to take some precautions. 'The crew was told to avoid lower-shielded areas of the space station out of an abundance of caution,' says Sandra Jones, a spokesperson for NASA’s Johnson Space Center. 'Certain areas provide less protection from radiation, such as the air lock, while other areas, such as crew quarters, provide enhanced protection. The crew was never in any danger, and the energy levels have since decreased.' Other satellite operators experienced greater difficulties. One company in the U.K., Sen, which streams 4K video from a satellite in low-Earth orbit, chose to power down its spacecraft for four days to prevent any damage from the storm, such as fried circuit boards or electronic failures. 'It was in an idle mode,' says Marcin Bujar, spacecraft operations lead at Sen. 'We just kept the bare minimum on—the flight computer and radio receiver.' This prevented the satellite from carrying out some tasks, including planned observations of flooding in South America and wildfires in Canada. 'It definitely had an impact,' Bujar says."

The latest #Spaceweather update from Spaceweather.com
"Because the sunspot is behind the edge of the solar disk, the flare was partially #eclipsed. It was probably even stronger than it appeared. 'X8.7' is almost certainly an underestimate of the flare's true strength.
"Extreme ultraviolet radiation from the flare ionized the top of Earth's atmosphere, causing a deep shortwave #RadioBlackout over the Americas. Ham radio operators, aviators and mariners may have noticed a sudden loss of signal at all frequencies below 30 MHz.
"Subatomic debris from this event might soon reach Earth, guided toward our planet by the #ParkerSpiral. Also, a #CME might be in the offing. Stay tuned for updates!
"EARTH IS CONNECTED TO SUNSPOT AR3664: Giant sunspot AR3664 is no longer facing Earth. That makes it extra dangerous. The #Carrington-class sunspot is passing over the sun's western limb--a region of the sun that is magnetically connected to our planet. Indeed, we are feeling the effects of that connection right now.
"What's causing this? Protons accelerated by solar flares in the magnetic canopy of #AR3664 are following the #ParkerSpiral back to Earth. Think of it as a magnetic superhighway. The arriving particles are funneled by our planet's magnetic field toward the poles where they ionize the atmosphere and interfere with the normal transmission of shortwave radio."

#SolarHam #Spaceweather Update:
Largest #SolarFlare Of #SolarCycle25 Observed
May 14, 2024 @ 17:05 UTC (UPDATED)
"The largest solar flare of the current solar cycle 25, and largest since 2017 was just observed around deparing #AR3664 off the west limb. The #X8.7 event peaked at 16:51 UTC (May 14) causing a strong R3 level radio blackout directly over North America. More to follow.
"And Then...
"An eruption in the vicinity of newly assigned #AR3682 measuring M4.4 was observed at 17:38 UTC (May 14). This event looks to be eruptive, meaning a #CME will be produced.
"Solar Cycle 25 just kicked it up a notch!"

"The largest solar flare of the current solar cycle 25, and largest since 2017 was just observed around deparing #AR3664 off the west limb. The #X8.7 event peaked at 16:51 UTC (May 14) causing a strong R3 level radio blackout directly over North America. More to follow.
"And Then...
"An eruption in the vicinity of newly assigned #AR3682 measuring M4.4 was observed at 17:38 UTC (May 14). This event looks to be eruptive, meaning a #CME will be produced.
"Solar Cycle 25 just kicked it up a notch!"
