Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-28T23:00Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2025-04-28T23:00:00-CME-001 (version 1)
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: First of three of a series of minor visible outflows seen to the north and northeast in SOHO LASCO C2 occurring between 2025-04-28T23:00Z and 2025-04-29T03:24Z; may possibly be associated with a minor filament eruption occurring near N40W05 as seen in GOES SUVI 284 imagery and SDO AIA 304 seen around 2025-04-28T20:00Z, but probably far-sided as suggested by the continued appearance of similar-looking outflows despite no major source signature on the Earth-facing disk; some weakly moving field lines high off the northern limb between 2025-04-29T02:00Z and 04:00Z may suggest far-sidedness of at least one of these events. This event is not seen in STEREO A COR2 due to a data gap.

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.
