🚨 BIG SUNSPOT ALERT 🚨
Sunspot 4366 didn’t exist days ago—now it’s nearly 10× wider than Earth and already fired off a triple-peaked M7–X1–M6 solar flare lasting over 6 hours. Its unstable magnetic field means more flares are likely. A radio blackout followed… and space weather may not be done yet.

Sunspot 4341 erupted Jan 18 (18:09 UTC), unleashing a long-lasting X1.9 flare captured by NASA Solar Dynamics Observatory. The blast ionized Earth’s atmosphere, causing shortwave radio blackouts across the Americas. Even bigger: a full-halo CME with an Earth-directed punch. Models show arrival early Jan 20, with a possible G3 geomagnetic storm and mid-latitude auroras.

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."

Major Solar Flare Alert (X7.1)

"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."

"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!"
My software has detected another solar flare. See the discontinuity in the green line around 9:30 AM Pacific time.
I originally wrote this code to keep tabs on a nearby utility pole which spends half the day arcing and splattering noise all over HF (see the red line), but it also monitors the noise floor (somewhat imperfectly, and for comparison with the utility pole spark-gap transmitter), and detection of solar flares has been an unexpected and amusing side-effect.
Interestingly, the flares themselves quite reliably cause a significant bump followed by chaotic behavior in the noise floor right when they happen. But when the charged particles arrive at our humble planet, they have the opposite effect: the noise floor drops and levels off.

"One, or perhaps a combination of at least two coronal mass ejections just reached both the #ACESpacecraft and #DSCOVRSpacecraft. The solar wind is fairly high nearing 700 km/s. A passage past our planet should take place within the next 45 minutes. Stay tuned..."

X3.9 Solar Flare / Radiation Storm
May 10, 2024 @ 08:50 UTC (UPDATED)
"The largest #SolarFlare yet produced by #AR3664 was just observed at 06:54 UTC. This X3.9 blast is associated with a Type II radio emission with an estimated velocity of 1248 km/s, along with a 10cm radio burst (TenFlare) measuring 900 SFU and lasting 16 minutes. A coronal mass ejection (CME) is now becoming visible and it appears the main bulk is heading to the west, but there will likely still be an Earth directed component. More to follow.
"Radiation Storm: The minor (S1) radiation storm threshold was reached at 13:35 UTC (May 10). This is possibly related to X3.9 flare this morning, or can also be due to a combination of all previous eruptions nearing Earth."

X2.2 #SolarFlare and Strong Storm Watch
May 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."

Another X-Flare!
August 7, 2023 @ 20:50 UTC
"Now located behind the west limb, AR 3386 just unleashed another X-Flare. The latest event was an X1.5 at 20:46 UTC (Aug 7). Due to the location behind the limb, it is possible that it could have been somewhat stronger than detected. Any associated CME will be directed away from Earth. More to follow whenever necessary."
"X-Flare!
August 5, 2023 @ 22:20 UTC
A strong X1.6 solar flare (R3 Level Radio Blackout) was just observed around AR 3386 approaching the west limb. The flare itself was long in duration with a peak flux at 22:21 UTC. Early indications are that a coronal mass ejection (#CME) will be associated with this event. Due to the location towards the west limb, most of the ejected material should be directed away from our planet. Coronagraph imagery will be required to determine if a glancing blow will be possible. This is the fifth strongest solar flare of the current cycle in terms of peak X-Ray flux."

#SolarHam is reporting that the flare came from region 3386.
Region 3386 is NOT directly Earth-facing -- moving to the far side. However, with the levels of recent #Solar activity, the #CME may affect Earth, even if it isn't a direct hit.
