Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-02-26T22:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
GOES: CCOR-1
Activity ID: 2026-02-26T22:00:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Faint CME first seen to the NNW part way into the FOV of SOHO LASCO C2. It is mostly seen to the NNW in GOES CCOR-1. The majority of the propagation of the CME is covered by real-time data gaps in SOHO LASCO C2/C3 and STEREO A COR2. A possible source of this CME is some very faint field line movement beyond the NNW limb best seen in GOES SUVI 284 starting around 2026-02-26T20:00Z.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type
