🚨 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)
October 1, 2024 @ 21:15 UTC
"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.

X5.8 #SolarFlare
May 11, 2024 @ 01:45 UTC
"While all of the excitement is surrounding the ongoing #geomagnetic storm, AR 3664 just produced a major X5.8 flare at 01:23 UTC. Updated imagery shows that a noteworthy #CME will be associated. More to follow!"

Incoming #CME Detected
May 10, 2024 @ 16:50 UTC (UPDATED)
"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..."
Also, chance of #XClassFlare is now at 75% (!!!)
