Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-12-29T06:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-12-29T06:24:00-CME-001 (version 1)
Source Location: S17E30
Active Region Number: 13939
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
FLR: Flare
DIM: Dimming
Morphology Keyword:
Note: This CME is visible to the southeast in STEREO A COR2 and as a partial halo directed towards the southeast in SOHO LASCO C2/C3 imagery. The source is likely related to an eruption and subsequent M2.0 flare from from Active Region 13939 (S17E30) starting around 2024-12-29T04:40Z as seen in GOES SUVI 131, 171, 195, 284, 304 imagery. A subsequent dimming is observed around the eruption site in GOES SUVI 195 imagery at this time as well.
