M6.7 Solar Flare Detected
|
March 18, 2024 @ 19:30 UTC
|
A moderately strong solar flare (M6.7) was just detected around AR 3615 near the southeast limb peaking at 19:19 UTC (Mar 18). More details to follow.
UPDATE: The solar flare itself was impulsive and a noteworthy CME is unlikely from this event. The active region continues to evolve and additional solar flares above the M1 level will be possible.

Active Regions to Watch / Partial Halo CME
|
March 17, 2024 @ 20:00 UTC
|
Good day. Solar activity on Sunday has so far been at low levels with numerous minor C-Flares detected around both newly assigned AR 3614 and AR 3615 (tentative). In the northeast quadrant, AR 3614 continues to turn back into view and is the return of old AR 3590 from the previous rotation. It appears to have decayed quite a bit while on the farside of the Sun, but could still remain a threat for an isolated M-Flare. In the southeast, a new sunspot region is turning into view and it may still be in a growth phase. It was the source of a mid level M-Flare on Saturday and will be monitored as the region moves further into view during the next 24 hours.
In other news, a filament eruption early Sunday morning beginning around 01:45 UTC (Mar 17) hurled a relatively faint, partial halo CME into space. The trajectory appears to be mostly south of the Sun-Earth line, however a weak Earth directed component may pass our planet within 72 hours.

M-Flare

March 16, 2024 @ 16:55 UTC
|
A region located just off the southeast limb produced a moderate M3.5 solar flare peaking at 16:35 UTC (Mar 16). We will get a better look at the source during the next 24-48 hours. Image below by SDO/AIA using the 131 angstroms channel.
