Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-10T10:45Z ( GOES: CCOR-1 )

All Detecting Spacecrafts:

GOES: CCOR-1

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2026-03-10T10:45:00-CME-001 (version 1)

Note Keyword:

FF: Event fails/disappears before exiting COR2

PRM: Prominence material (filamentary structures)

Source Signature Keyword:

FIL: Filament eruption

OFL: Moving/Opening field lines

Morphology Keyword:

Note: CME first seen to the NW by GOES CCOR-1 beginning at 2026-03-10T10:45Z, as well as by SOHO LASCO C2/C3 and STEREO A COR2 in later frames. The source of this event was a far sided prominence eruption seen from beyond the NW limb in GOES SUVI 304. Field line opening is also visible in GUES SUVI 195 and 284. This eruption began at approx. 2026-03-10T07:30Z, but did not fully detach from the disk until approx. 2026-03-10T09:57Z.
