Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2024-04-09T02:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2024-04-09T02:12:00-CME-001 (version 1)
Source Location: N15W68
Active Region Number: 13624
Note Keyword:
DFL: Likely deflection of the event within the FOV
GAP: Data gap
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
O: Other
Note: Slow CME seen to the NW in all coronagraphs, but not in many available frames of STEREO COR2A due to an ongoing campaign giving us one image per hour. The source for this CME is unclear, and could be linked to a tiny filament eruption from AR 3624 (N15W68) first observed in SDO AIA 193 at 2024-04-08T20:30Z and observed as additional field line movement in GOES SUVI 284. However, this source occurs well before the first sighting in coronagraph imagery (around 4 hours), so it is noted as the only observed source in proximity.
