Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-19T02:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-03-19T02:24:00-CME-001 (version 1)
Note Keyword:
3P: 3-part structure CME
SB: Streamer Blowout following CME
Source Signature Keyword:
OFL: Moving/Opening field lines
DIM: Dimming
Morphology Keyword:
Note: Bright streamer blowout CME to the NE in SOHO LASCO C2, C3, and STEREO A COR2 imagery. The CME is visibly wider in STEREO A COR2 imagery than in SOHO imagery. The source of this CME appears to be a complex series of eruptions beginning with an eruption near N05E05 starting around 2025-03-19T00:39Z. This eruption may have triggered additional instability of nearby magnetic field line foot points, which may be associated with the streamer itself. Dimming is clearly seen to the east of the initial eruption location starting around 2025-03-19T06:00Z. It is also around this time that the CME appears to begin to speed up in the SOHO field of view with a more clear/defined front appearing around this time as well.
