#SpaceWeather News for Dec. 7, 2025
"A SOLAR STORM IS HEADING DIRECTLY FOR EARTH: Strong G3-class #GeomagneticStorms are possible on Dec. 9th when a full-halo #CME is expected to strike our planet. The storm cloud was hurled in our direction on Dec. 6th by an almost- #XClass #SolarFlare. Full story @ Spaceweather.com."

Another #XFlare / Severe #GeomagneticStorm Watch
via #SolarHam
October 9, 2024 @ 15:50 UTC (UPDATED)
"A moderate (S2) to Strong (S3) radiation storm remains in progress following the energetic X-Flare produced by #AR3848.
"A severe (G4) geomagnetic storm watch was officially added beginning tomorrow when the fast moving CME associated with the flare event is expected to sweep past Earth. While there are no guarantees, a repeat of the geomagnetic storm and aurora event back in May could be on the horizon.
"Oh... and an impulsive X1.4 solar flare was observed around departing AR 3842 at 15:47 UTC (Oct 9)."

#Spaceweather Update (via #SolarHam )
Major #SolarFlare and #CME
September 14, 2024 @ 19:05 UTC"A major X4.5 solar flare was produced by #AR3825 on September 14th, 2024 @ 15:29 UTC. The event was associated with a fast moving halo coronal mass ejection (CME). Although the eruption is directed mostly to the east, the western flank of the plasma cloud does appear Earth directed. A passage past Earth will be possible within 48 hours. I would expect a #GeomagneticStormWatch to be added later today for #September16th. Stay tuned for the latest updates."

No #GeomagneticStorm predicted yet. But with former #AR3664 (now #AR3697) belching out big flares, we might be in for another #Aurora treat soon...

#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."

#SolarHam summary of the #auroras
MAY The 3664th
May 13, 2024 @ 00:45 UTC
"I just want to say thank you for your support the past few days. I did not get much sleep as SolarHam is a one person operation, however the Extreme #GeomagneticStorm generated a record number of visitors to the website. I appreciate everybody who continues to follow SolarHam on both the main website and on social media. Hard to believe I have been doing this now for over 18 years!
"I would like to share with you an article I wrote detailing the extreme geomagnetic storm titled 'May the 3664th'. I compiled data and imagery, all in chronological order to show how the events unfolded. I also added a small fraction of the aurora imagery that was submitted so far. Thanks again!"

X2.2 #SolarFlare and Strong Storm WatchMay 9, 2024 @ 09:10 UTC (UPDATED)
"AR 3664 does it again with a long duration X2.2 solar flare peaking at 09:13 UTC (May 9). Coronal dimming is already evident meaning this flare will likely be the source of a fourth Earth directed #CME.
"The #GeomagneticStorm watch for this weekend was upgraded to the Strong (G3) level and this latest event could add even more fuel to the storm. Aurora sky watchers rejoice, it may be a great weekend!
"Fourth Halo CME Confirmed: Updated coronagraph imagery following the X2.2 solar flare confirms that a fourth halo CME was produced and appears Earth directed. With now four plasma clouds expected to pass Earth, the chances for a strong geomagnetic storm this weekend just increased."

Ancient #SolarStorm smashed Earth at wrong part of the sun's cycle — and scientists are concerned
The 9,200-year-old storm left researchers with a stark conclusion: We are not ready for the next one.
By Brandon Specktor
published January 28, 2022"An extremely powerful solar storm pummeled our planet 9,200 years ago, leaving permanent scars on the #ice buried deep below #Greenland and #Antarctica.
"A new study of those ancient ice samples has found that this previously unknown storm is one of the strongest outbursts of solar weather ever detected and would have crippled modern communications systems if it had hit Earth today.
"But perhaps most surprising, the massive storm appears to have hit during a #SolarMinimum, the point during the sun's 11-year cycle when solar outbursts are typically much less common, according to the study, published Jan. 11 in the journal Nature Communications. Because of this unexpected discovery, the study researchers are concerned that devastating solar storms could hit when we least expect them — and that Earth might not be prepared when the next big one arrives.
"Solar storms occur when magnetic field lines on the sun's corona (the outermost part of the sun's atmosphere) become tangled up and then violently snap back into place. This sudden magnetic reconnection can release huge gouts of plasma and magnetic field known as coronal mass ejections (CMEs), which surf across space on the sun's ever-gusting #SolarWind.
"If a powerful #CME passes over Earth, it can compress the planet's #MagneticShield, causing what's known as a #GeomagneticStorm.
"Mild geomagnetic storms can damage #satellites and interrupt radio transmissions; severe storms, like the 'Halloween storms' of 2003, can cause widespread #PowerOutages across the world and permanently damage #ElectricalInfrastructure, such as power transformers. Some researchers fear that a sufficiently large solar storm could also ravage the world's undersea internet cables, resulting in an '#InternetApocalypse' that leaves huge chunks of the world population disconnected for months.
"CME outbursts typically peak every 11 years or so, when the sun enters the part of its natural activity cycle known as the solar maximum — the time when magnetic activity in the corona is in high gear.
"Today, satellites can monitor solar outbursts directly. But finding evidence of ancient storms requires some atomic detective work. The authors of the new study looked for evidence of special particles known as #CosmogenicRadionuclides — essentially, radioactive isotopes (versions of elements) created when charged solar particles collide with elements in Earth's atmosphere.
"These radioactive particles can appear in natural records, like tree rings and ice cores. In the study, the authors looked at the latter, analyzing several cores drilled in Antarctica and Greenland. Cores from both locations showed a remarkable spike in the radionuclides beryllium-10 and chlorine-36 around 9,200 years ago, indicating that a powerful solar storm swept across Earth at that time.
"Further analysis of the cores showed that the storm was particularly powerful — perhaps on a par with the most powerful solar storm ever detected, which occurred during a solar maximum between the years 775 B.C. and 774 B.C.
"The newly discovered storm's occurrence during a solar minimum, when magnetic activity on the sun should be low, left the study authors puzzled and alarmed.
"'This [storm] further pushes the magnitude of a potential worst-case scenario for [solar storm] events,' the researchers wrote in the study.
"According to the study authors, it is now essential for researchers to detect more ancient, extreme storms in the ice-core and tree-ring records, to determine if there is some sort of pattern beyond the sun's 11-year cycle that dictates when the most extreme storms will occur."
