Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-09T06:36Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

STEREO A: SECCHI/COR2

Activity ID: 2025-05-09T06:36:00-CME-001 (version 1)

Note Keyword:

Source Signature Keyword:

OFL: Moving/Opening field lines

Morphology Keyword:

F: Flux Rope

Note: Narrow CME seen to the west in SOHO LASCO C2 and GOES CCOR1 to the west but not seen well in STEREO A COR2; the source could be associated with a minor eruption from Active Region 14079 (N08W56) but may also be emanating from behind the western limb; there are weakly opening field lines off the western limb seen in GOES SUVI 284 but they do not neatly trace back to an eruption from AR 4079, so analysis is speculative.
