Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-19T17:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-04-19T17:00:00-CME-001 (version 2)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Semi-faint CME to the south in SOHO LASCO C2 and C3 (also visible in GOES-19/CCOR-1). The source is field line movement seen to the south beyond the limb in SDO/AIA 171 and 193 as well as in GOES SUVI 335 starting around 2025-04-19T16:48Z. This is likely a far-sided event. There is no STEREO A imagery for this event due to a data gap.
