Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-07T14:30Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

GOES: CCOR-1

Activity ID: 2026-03-07T14:30:00-CME-001 (version 2)

Note Keyword:

Faint: Faint event; may affect type assignment

GAP: Data gap

Source Signature Keyword:

Morphology Keyword:

L: Loop

Note: A loop-like front to the ENE that is originally seen in SOHO LASCO as the southern part of a messy strange front conglomerate (likely two combined fronts). It is not seen in STEREO A because of a nighttime data gap. It is seen the clearest in GOES CCOR-1. The source of this CME is not clear.

Only plane-of-sky analysis with GOES CCOR-1 is possible for this event.	Not modeled		Anna Chulaki on 2026-03-07T20:14Z
