Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-26T19:15Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
SOHO: LASCO/C2
SOHO: LASCO/C3

FS: Flux Rope and Shock Candidate
Note: Bright CME seen to the southeast starting near 2026-03-26T19:15Z in GOES CCOR-1 and late in SOHO C2/C3 due to a data gap; the source is likely far-sided as determined from the lack of moving or opening field lines on the Earth-facing disk as seen in GOES coronagraph imagery between 17:00 and 19:00Z. The CME is comprised of a brighter central portion and an asymmetric shock portion which is fainter and overtakes the brighter portion in the imagery.
