All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2023-04-29T02:23:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
Source Signature Keyword:
BR: Brightening
DIM: Dimming
Morphology Keyword:
L: Loop
Note: Faint CME with what appears to be multiple fronts seen to the S/SW in STEREO A COR2 imagery and more generally to the South in SOHO LASCO C2 & C3 imagery. There is a fairly wide source region with associated brightening and dimming ranging from -20 to -40 degrees latitude and -10 to +30 degrees longitude starting around 01:30Z. This eruption encompasses AR13288. It is best seen in SDO/AIA 193, 304, and 211 as well as STEREO A EUVI 195.
