SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2026-03-16T13:26:00-CME-001 (version 1)
Source Location: S15E19
Active Region Number: 14392
Note Keyword:
GAP: Data gap
HAL: Halo CME
Source Signature Keyword:
FLR: Flare
PEA: Post eruption arcade
EUVW: EUV Wave
Morphology Keyword:
Note: This CME is visible as a partial halo directed to the northeast in SOHO LASCO C2/C3 and GOES CCOR-1 imagery. This event is not seen in STEREO A COR2 imagery in real-time due to a data gap starting at 2026-03-14T12:09Z. The source is an M2.7 flare and eruption from Active Region 14392 (S15E19) starting around 2026-03-13T12:00Z as seen in GOES SUVI 131/171/195/284/304 imagery. A corresponding EUV wave is observed moving primarily northwest of the eruption site in GOES SUVI 195/304 imagery, with post-eruptive arcades visible starting around 2026-03-16T13:00Z.

Preliminary measurement following the brightest leading edge portions seen to the north and to the southeast. The measured parameters were based on the source location and best fit in SOHO LASCO C2 and GOES CCOR-1 imagery. Due to a data gap in STEREO A COR2 at the time of this event, a triangulated measurement was not available and the measured parameters may vary as a result. |
