Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-22T14:48Z ( SOHO: LASCO/C2 )

All Detecting Spacecrafts:

SOHO: LASCO/C2

SOHO: LASCO/C3

Activity ID: 2025-03-22T14:48:00-CME-001 (version 1)
Source Location: N18E52

Note Keyword:

Source Signature Keyword:

PEA: Post eruption arcade

OFL: Moving/Opening field lines

DIM: Dimming

Morphology Keyword:

Note: This CME is visible to the northeast in SOHO LASCO C2/C3 imagery. The source is likely related to an eruption centered near N18E52 starting around 2025-03-22T13:00Z as seen in SDO AIA 131, 171, 193, 304 imagery. Dimming is visible north of the eruption site in SDO AIA 171 and 193 imagery starting around 2025-03-22T14:00Z and an opening of field lines can be observed over the northeast limb in GOES SUVI 284 imagery at this time. Additionally, post-eruptive arcades begin to form around 2025-03-22T14:30Z in SDO AIA 171 and 193 imagery.
