Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-26T14:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-03-26T14:36:00-CME-001 (version 1)
Source Location: N20E70
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
L: Loop
Note: Bright CME first seen in the NE by SOHO LASCO C2 beginning at 2025-03-26T14:36Z. This CME likely has an earlier start time that is obscured by a SOHO data gap from 26/11:36Z to 26/14:36Z. This CME is not seen at all in STEREO A COR2 due to a data gap beginning at 26/12:38Z. The source of this event is field line opening seen along the NE limb (approx. N20E70) beginning at approx. 26/13:28Z as seen in GOES SUVI 171 and 195.
