Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2023-12-21T06:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2023-12-21T06:09:00-CME-001 (version 1)
Source Location: S11W61
Active Region Number: 13519
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
Morphology Keyword:
Note: This CME is visible to the west in STEREO A COR2 coronagraph imagery. This event is not seen in SOHO LASCO C2/C3 due to a SOHO keyhole maneuver in which no LASCO imagery is available. The source is likely an eruption and subsequent M4.2 flare from AR 3519 (S11W61) starting around 2023-12-21T05:30Z as seen in SDO AIA 131, 171, 193, 304 imagery. Post-eruptive arcades are visible in SDO AIA 171 and 193 imagery starting around 06:30Z.

Since SOHO LASCO C2/C3 imagery is missing for the duration of this event, this measurement relies on STEREO A COR2 alone. It is possible the parameters vary slightly as a result. 1: Result 1 (2.0 AU)
