Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-14T05:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-03-14T05:48:00-CME-001 (version 2)
Active Region Number: 14384
Note Keyword:
DPL: CME exhibits dimpled front
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: Faint CME observed to the NW in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2. The source longitude is unclear, but there is an eruption observed on/around the NW limb in GOES SUVI 284 starting around 2026-03-14T05:48Z, potentially associated with AR 14384.
