Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-05T09:48Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2025-04-05T09:48:00-CME-001 (version 3)

Note Keyword:

DFL: Likely deflection of the event within the FOV

Faint: Faint event; may affect type assignment

OFL: Outflowing material at the back of the CME

OVR: Event partially overlaps with another CME

Source Signature Keyword:

FIL: Filament eruption

Morphology Keyword:

F: Flux Rope

Note: Faint northward CME with messy multiple fronts, overlapping with 2025-04-05T04:00Z and 2025-04-05T06:36Z CMEs (this overlap makes analysis difficult). The start of the CME is likely significantly earlier, around 2025-04-05T08:36Z, but its front in the early timestamps is very difficult to discern because of the overlap. The source could be the large filament behind the northeast limb moving northward, as seen in SDO AIA 304 and GOES SUVI 304 after 2025-04-05T05:00Z, but it is unclear whether this filament is the source of this CME - or the 2025-04-05T06:36Z CME.
