Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-04T11:48Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

STEREO A: SECCHI/COR2

Activity ID: 2025-06-04T11:48:00-CME-001 (version 1)
Source Location: N23E45

Note Keyword:

Faint: Faint event; may affect type assignment

FF: Event fails/disappears before exiting COR2

OFL: Outflowing material at the back of the CME

Source Signature Keyword:

PEA: Post eruption arcade

FIL: Filament eruption

OFL: Moving/Opening field lines

DIM: Dimming

Morphology Keyword:

O: Other

Note: Narrow very faint CME with a fuzzy front seen to the northeast in SOHO LASCO and STEREO A COR2 coronagraphs and obscured by the pylon in GOES CCOR-1. Its source is the filament eruption centered ~(N23E45) starting at 2025-06-04T10:17Z as seen in SDO AIA 193/304 as dimming and as opening of field lines on the northeast limb in STEREO A EUVI 195.
