Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-07-26T16:23Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
Activity ID: 2026-07-26T16:23:00-CME-001 (version 1)
Source Location: S05E03
Active Region Number: 14494
Note Keyword:
GAP: Data gap
Source Signature Keyword:
FLR: Flare
Morphology Keyword:
Note: CME first seen to the E in STEREO A COR2 starting at 2026-07-26T16:23Z. It is not seen in GOES CCOR-1 and is covered by a real-time data gap in SOHO LASCO C2/C3. The source of this CME is likely associated with an impulsive M3.2 flare from AR 14494 (S05E03) that peaked at 2026-06-27T15:28Z. The flare is best seen in SDO AIA 131.
