Activity ID: 2024-08-26T12:12:00-CME-001 (version 1)
Note Keyword:
FOV: Front Bright front; may be evidence of pileup
SB: Streamer Blowout following CME
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
L: Loop
Note: Streamer blowout CME to the S/SE in SOHO LASCO C2, C3, and STEREO A COR2 imagery. The start time of the CME could be as early as ~10Z, as that's when the shape first starts appearing in difference imagery, however it doesn't quite start progressing out in the field of view until roughly 12:12Z. The source appears to be moving/opening field lines visible in GOES SUVI 284 in the SE quadrant of the Earth-facing disk with notable changes in the corona's structure over the course of several hours. Most notably, these changes are visible starting around 14:00Z. Brightening is visible on the disk starting around 15:00Z with continued restructuring of the corona for several hours after. Additionally, the CME structure appears to be visible in the field lines off the SE limb, fairly stationary as early as 2024-08-25T17:00Z and is released during this restructuring starting around 2024-08-26T12:00Z.
