Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-05-25T23:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-05-25T23:24:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
Morphology Keyword:
L: Loop
Note: Faint loop CME first seen to the NW by SOHO LASCO C2 beginning at 2026-05-25T23:24Z, as well by SOHO LASCO C3 and GOES CCOR-1 in later frames. This event is not clearly seen in STEREO A COR2 due to a data gap from 2026-05-25T20:53Z to 2026-05-26T01:23Z. The source of this event is likely continued far sided outflow following earlier CME: 2026-05-25T22:12Z.
