Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-10T12:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
Activity ID: 2026-03-10T12:24:00-CME-001 (version 2)
Source Location: N13E70
Active Region Number: 14389
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
Source Signature Keyword:
FLR: Flare
OFL: Moving/Opening field lines
Morphology Keyword:
Note: Faint CME first seen to the Northeast by SOHO LASCO C2 beginning at 2026-03-10T12:24Z. This front fades very quickly and is therefore not visible in SOHO LASCO C3, STEREO A COR2 or GOES CCOR-1. The source of this event is a C2.4 flare from Active Region 14389 (N13E70) peaking at 2026-03-10T12:04Z as seen in GOES SUVI 131, along with field line opening seen in GOES SUVI 193 and 284. It appears that this eruption mostly fails and falls back towards the solar disk.
