Another X-Flare

"X-Flare Alert. Sunspot region 4114 just produced an X1.9 solar flare peaking at 23:50 UTC (Jun 19). Coronal dimming is not yet evident meaning a noteworthy #CME is unlikely. More to follow whenever necessary."

Millions of Americans Told to Stay Indoors After Rare X1.2-Class Solar Flare Eruption
Story by Michaele Allies
June 17, 2025
"On June 17, 2025, the Sun unleashed a powerful X1.2-class solar flare from sunspot region 4114, which was directly facing Earth. This intense burst of energy prompted warnings for millions of Americans to stay indoors for three days due to increased radiation risks and communication disruptions. The flare caused immediate effects such as radio blackouts, especially over the Pacific Ocean and Hawaii, impacting aviation and amateur radio operations.
"This event underscores the importance of understanding solar flares, as they can significantly affect Earth's environment and modern technology, including satellites, power grids, and navigation systems. #NASA’s Solar Dynamics Observatory [#SDO] captured detailed imagery of the flare, while #NOAA issued alerts to help mitigate its impact. As solar activity intensifies during this solar cycle, such events remind us of the Sun’s power and the need for preparedness against space weather threats."

October 24, 2024 @ 04:25 UTC (UPDATED)
"A returning sunspot region now reassigned AR 3869 just produced a strong X3.3 solar flare at 03:57 UTC (Oct 24). A type II radio emission with an estimated velocity of 610 km/s was recorded. This event will be associated with a coronal mass ejection (#CME) based on dimming following the event. Because the flare location is located off the east limb, it will be directed mostly away from Earth. A further update will be provided once coronagraph imagery is updated.
"CME Update #2: Despite the X3.3 solar flare being located close to the southeast limb, the resulting halo coronal mass ejection (CME) appears to be wide enough to include an Earth directed component. If so, a passage past our planet will be possible within 48-72 hours. A further update will be provided later today once an official tracking model is available.
"A minor (G1) geomagnetic storm watch was officially added for Saturday, October 26th. The edge of the X3.3/Halo CME is expected to deliver a glancing blow to our geomagnetic field. A prolonged period of southward Bz following a potential passage could increase the chances of storming and visible #aurora at higher latitudes. Stay tuned this weekend for further updates."

The sun is reaching the peak of its 11-year activity cycle. Scientists said Tuesday that they conclude the sun is at the peak of "Cycle 25" and will remain there for another year or so before activity starts to subside. That peak of activity has resulted in brilliant auroral displays, but solar storms that produce auroras also threaten satellites and the electrical grid. https://www.space.com/solar-cycle-25-max-phase-more-sun-storms

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)."

Major Solar Flare (X9)
October 3, 2024 @ 13:50 UTC (UPDATED)
via #SolarHam
"A major X9.0 solar flare was just detected around Earth facing sunspot region #AR3842 at 12:18 UTC (Oct 3). This is the strongest X-Ray event of the current solar cycle. More details to follow regarding a possible CME.
"#CME Update: A coronal mass ejection (CME) with a halo signature is evident following the major X9.0 solar flare this morning. Because the source region AR 3842 is directly facing Earth, the plasma cloud appears to be aimed directly towards our planet. A further update will be provided later today once a CME tracking model becomes available. Please note that a faint CME associated with the X7 event on October 1st is expected to pass our planet sometime during the next few days.
"Aurora sky watchers at middle to high latitudes should have their camera batteries charged up should geomagnetic storming be observed as forecast."

"The second strongest detectable solar flare of the current solar cycle 25 was just observed around Earth facing #AR3842 peaking at 22:20 UTC (Oct 1). A type II radio emission with an estimated velocity of 1246 km/s was recorded. Stay tuned to SolarHam.com for the latest details regarding a possible Earth directed #CME."

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."

X1.3 Flare and CME Likely
August 8, 2024 @ 19:35 UTC
"An X1.3 solar flare was detected around #AR3777 at 19:35 UTC. A type II radio emission with an estimated velocity of 1026 km/s was recorded. Coronal dimming is already evident meaning a coronal mass ejection (#CME) is likely. Due to the event location facing Earth, it will more than likely be directed towards our planet. More details to follow."

Solar Cycle 25 continues the trend of much higher sunspot activity than originally forecast, with the latest sunspot number for July (196.5) nearly double the predicted value (106.4).
The current #SolarCycle25 started in 
2019. It is not expected to end for another six years but the first signs that the next #SolarCycle is beginning have been spotted by researchers from the University of #Birmingham and presented at the @royalastrosoc National #Astronomy Meeting in Hull. "We're likely seeing the first traces of Cycle 26, which won't officially start until about 2030." https://www.sciencedaily.com/releases/2024/07/240719123850.htm

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."
Solar Cycle 25 continues to be far more active than originally forecast; the sunspot number for May '24 was ~70% higher than predicted, and well above the high end of the forecast for the Cycle 25 solar maximum, which is still more than a year away. #spaceweather #spacewx #solarcycle #solarcycle25 #cycle25
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."
#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!"
@g7izu Sounds like #SolarCycle25 isn't over yet...!
