All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2026-03-16T09:24:00-CME-001 (version 1)

Note: This CME is visible to the southeast in SOHO LASCO C2/C3 imagery. This event is not seen in real-time by GOES CCOR-1 or STEREO A COR2 imagery due to data gaps starting at 2026-03-14T23:15Z and 2026-03-14T12:09Z, respectively. The source is an eruption centered near S12E70 starting around 2026-03-16T09:00Z as seen in GOES SUVI 131/171/195/284/304 imagery.
