Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-13T20:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2026-03-13T20:48:00-CME-001 (version 2)
Source Location: S15E53
Active Region Number: 14392
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: Faint CME first seen to the SE by SOHO LASCO C2 beginning at 2026-03-13T20:48Z but fading before exiting the field-of-view in C2 and is therefore not visible in SOHO LASCO C3, STEREO A COR2 or GOES CCOR-1. The source of this event is a C8.9 flare from Active Region 14392 (S15E53) which peaks at 2026-03-13T20:23Z. This flare can be seen in GOES SUVI 131, along with dimming and field line features seen in GOES SUVI 195 and 284.
