Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-14T11:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-03-14T11:48:00-CME-001 (version 4)
Source Location: N45W25
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
PEA: Post eruption arcade
BR: Brightening
Morphology Keyword:
J: Jet
Note: The earliest in a series of multiple outflowing extremely narrow fronts seen in SOHO LASCO and GOES CCOR-1 coronagraphs to the NNW. Not seen in STEREO A COR2 running difference imagery, which is very sporadic and low quality due to an ongoing campaign. The potential source is a high northern latitude eruption seen in STEREO A EUV 195 starting at 2026-03-14T10:45Z.
