Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-06-25T23:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
Activity ID: 2026-06-25T23:48:00-CME-001 (version 1)

Note: CME first seen to the W in SOHO LASCO C2 starting at 2026-06-25T23:48Z. This leading edge is extremely faint in SOHO LASCO C2 and is not seen in SOHO LASCO C3 or GOES CCOR-1. The front is best seen to the W in STEREO A COR2. Measurement indicates that the source of this CME is far-sided, but the start time is covered by data gaps in STEREO A EUVI.
