Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-27T23:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-03-27T23:12:00-CME-001 (version 1)
Source Location: S35E35
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: Faint CME visible to the SE in SOHO LASCO C2/C3 and GOES CCOR-1. The CME is partially obscured by the pylon in SOHO LASCO C3. Not visible in STEREO A COR2 due to a data gap starting at 2026-03-27T16:53Z. The potential source is a filament eruption starting around 2026-03-27T20:36Z centered around S35E35 as seen in GOES SUVI 195/304.
