All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2023-09-21T21:12:00-CME-001 (version 2)
Source Location: S25E25
Active Region Number: 13439

Note Keyword:

GAP: Data gap

Source Signature Keyword:

BR: Brightening

DIM: Dimming

Morphology Keyword:

U: Unknown

Note: CME seen in the SE of SOHO LASCO C2/C3. Not visible in STEREO A imagery due to data gap. Source is eruption starts around 2023-09-21T20:09Z and is best seen in SDO AIA 193/304. Material can be seen lifting off in SDO AIA 304 and an eruption with dimming and post eruptive loops that can be best seen in SDO AIA 193. Eruption is also visible in SDO AIA 94, where the eruption can also be seen deflecting towards the south.
