Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-12-10T18:12Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

Activity ID: 2024-12-10T18:12:00-CME-001 (version 2)
Source Location: S18E70
Active Region Number: 13922

Note Keyword:

DFL: Likely deflection of the event within the FOV

GAP: Data gap

OVR: Event partially overlaps with another CME

Source Signature Keyword:

FLR: Flare

OFL: Moving/Opening field lines

BR: Brightening

EUVW: EUV Wave

Morphology Keyword:

Note: This CME is visible to the S/SE in SOHO LASCO C2 and C3 imagery. There is a data gap in STEREO A COR2 imagery for this event. The source appears to be an M1.6 class flare from AR 13922 (S18E70) with a sympathetic eruption to the west of this region starting around 2024-12-10T17:58Z as seen in GOES SUVI 131, 304, and 284. Moving/opening field lines are visible along the limb as well as a minor EUV wave to the south along the limb as seen in GOES SUVI 284 and 195.
