Latest Space Weather News
Near X-Flare
February 3, 2025 @ 04:15 UTC
A solar flare measuring M8.8 was just detected around AR 3981 peaking at 03:58 UTC (Feb 3). This is the strongest flare yet from this region in terms of peak X-Ray flux. The flare itself was impulsive and will likely not be the source of a noteworthy coronal mass ejection. More flaring will remain likely around the region as it continues to expand in both size and magnetic complexity.

Space Weather Update
February 2, 2025 @ 14:15 UTC (UPDATED)
Solar activity increased even further on Sunday morning with now six M-Flares and counting. The largest so far was a rapid M5.1 at 14:04 UTC (Feb 2) around AR 3977. AR 3981 located in the northeast quadrant is growing rapidly and chipped in with a few M-Flares including an M3.0 flare at 10:12 UTC. That event was associated with a Type II radio emission, but so far a CME related to this event does not appear evident. Stay tuned for more updates.

Coronal Hole Stream
February 1, 2025 @ 13:10 UTC
A solar wind stream flowing from tomahawk shaped coronal hole #11 is now moving past Earth around 600 km/s. Currently active (Kp4) geomagnetic activity is being observed at higher latitudes. With any help from the interplanetary magnetic field, minor (G1) storm conditions could still be observed at some point on Saturday.

Also notice a pair of filaments currently located in the southern hemisphere. For now they remain magnetically anchored in place. Image by SDO/AIA.

M6.7 Solar Flare / CME Likely
January 31, 2025 @ 14:25 UTC (UPDATED)
A moderately strong solar flare measuring M6.7 (R2 Radio Blackout) was detected at 14:06 UTC (Jan 31). The source was AR 3978 with interaction between AR 3976 located in the northeast quadrant. The event is associated with a 10cm Radio Burst (TenFlare) measuring 280 solar flux units (SFU) and lasting 14 minutes. A type II radio emission with an estimated velocity of 673 km/s was recorded. AIA 193 imagery shows plasma movement following the event so a coronal mass ejection (CME) will be likely. The trajectory should be mostly to the east, however updated coronagraph imagery will be required to determine if an Earth directed component is associated. Stay tuned for updates.

CME UPDATE: As I suspected, the long duration M6.7 solar flare around AR 3978 did produce a coronal mass ejection (CME) that is heading to the northeast and likely away from Earth. There is currently a gap in available imagery courtesy of LASCO C3, however STEREO Ahead COR2 does capture the CME in full. Click HERE for video.

Another update will be provided once LASCO C3 imagery is backfilled should a faint Earth directed component be associated.

Space Weather Update
January 31, 2025 @ 12:30 UTC
Good morning and welcome to the final day of January.

Below is a look at the eastern half of the visible solar disk, including the large sector of sunspots comprised of at least three or more separate active regions in the northeast quadrant. New spot growth was observed to the north of AR 3976 and 3978 and they appear to be magnetically independent from the other regions. It is possible that at least one of those groups could receive their own active region status. Regardless, the threat for M-Class solar flares has increased to 55% according to the latest SWPC update with AR 3976 being the most likely source.
