Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-03-19T04:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2026-03-19T04:36:00-CME-001 (version 1)
Source Location: S40E15
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: Faint CME first seen to the SE by SOHO LASCO C2 beginning at 2026-03-19T04:36Z, as well as by STEREO A COR2 and GOES CCOR-1 in later frames. This event is obscured by the pylon in SOHO LASCO C3. The source of this CME is a faint region of dimming beginning at approx. 2026-03-19T03:56Z located at approx. S40E15 as seen in GOES SUVI 195. This event was likely defected due to its proximity to a coronal hole.
