Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-03T12:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-03-03T12:36:00-CME-001 (version 1)
Source Location: N15E05
Active Region Number: 14378
Note Keyword:
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: CME visible to the NNW in SOHO LASCO C2/C3 and GOES CCOR-1 and the NNE in STEREO A COR2. The source is not very clear in available EUV imagery, but may be an eruption from the vicinity of AR 14378 (approximately N15E05). This eruption is not clearly seen in GOES SUVI imagery, but moving field lines can be seen from this region starting around 2026-03-03T08:35Z in STEREO A EUV 195.
