All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-03-16T15:24:00-CME-001 (version 2)
Source Location: N50W10
Note Keyword:
GAP: Data gap

Note: Bright, slow CME first seen to the north in SOHO LASCO C2 beginning at 2026-03-16T15:24Z, as well as by SOHO LASCO C3 and GOES CCOR-1 in later frames. This event is not seen in STEREO A COR2 due to a data gap which began at 2026-03-16T14:53Z. The source of this event is faint dimming and field line movement seen in GOES SUVI 193/284 located at approx. N50W10 beginning at approx. 2026-03-16T14:00Z.
