Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-19T23:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-03-19T23:48:00-CME-001 (version 1)
Source Location: S07W100
Note Keyword:
3P: 3-part structure CME
COL: Possible collision with previous CME
Source Signature Keyword:
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
F: Flux Rope
Note: Faint loop CME visible to the northwest in SOHO LASCO C2/C3, with a faint flux rope feature more visible in STEREO A COR2 imagery. The source is the ejection of material from just beyond the southwest limb, first distinctly seen as a distinct instance of opening field lines and ejecta starting around 2025-03-19T23:15Z in GOES SUVI 304 and 284 imagery. Post-eruptive brightening extends onto the disk spanning from about S10 to S15 and W80 to W90, as seen in SDO AIA 304 at 2025-03-19T23:40Z. Associated surrounding field line movement extends into the northern hemisphere on or beyond the western limb, and some northern deflection occurs as the material erupts.

CME Analysis M2M_CATALOG LE true SWPC_CAT 73.0 8.0 627.0 C 28.0 2025-03-20T06:32Z Measurement using best fit between SOHO LASCO C3 running difference and STEREO A COR2 difference imagery, as well as the approximated location of source seen in available UV imagery of the Earth-facing disk. The quality and cadence of STEREO A COR2 imagery was affected during time of analysis due to a campaign scheduled to last from 2025-03-18 to 2025-03-24. 1: Result 1 (2.0 AU)
