Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-08T10:09Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-07-08T10:09:00-CME-001 (version 3)
Note Keyword:
GAP: Data gap
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME visible to the west in GOES CCOR-1 and STEREO A COR2 imagery. This CME was not visible in SOHO LASCO C2/C3 in real-time due to a data gap from 2026-07-08T05:48Z to 2026-07-08T15:48Z. The source is likely an eruption with opening field lines starting around 2026-07-08T08:25Z in STEREO A EUV 195 imagery. The exact source location on the disk as seen from STEREO A is unclear, as the source is near the west limb.
