Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-05-23T20:30Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2026-05-23T20:30:00-CME-001 (version 1)
Note Keyword:
DPL: CME exhibits dimpled front
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
O: Other
Note: CME seen to the NW in SOHO LASCO and GOES CCOR-1 with an irregular front overlapping with earlier NW CMEs. The front is likely also seen to the NW in a couple of timestamps of STEREO A COR2. Its source is not clear: one source could be a minor eruption in AR 14441 (N8W68)seen at 2026-05-23T10:45 in STA EUV 304/195 seen as brightening and dimming but it is not confirmed by the fit with coronagraphs. Another source could be AR 14436 (N18W110) which has been showing signs of activity for many hours.
