Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-24T19:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-03-24T19:24:00-CME-001 (version 1)
Note Keyword:
GAP: Data gap

OFL: Moving/Opening field lines
Morphology Keyword:
Note: Narrow CME (less than ten degree half-width) first seen to the SE in SOHO LASCO C2 started at 2025-03-24T19:24Z. CME is also seen to the SE in SOHO LASCO C3 but is not seen in STEREO A COR2 due to a data gap beginning 2025-03-24T16:09Z. The source of this CME is possibly a small amount of ejecta from beyond the SE limb best seen in SDO AIA 304 starting at 2025-03-24T19:06Z. Some very faint field line movement from beyond the SE limb can also be seen in SDO AIA 171 and SDO AIA 193 starting around 2025-03-24T19:04Z.

Prime?"primary flag" which is either True or False. If there are multiple CME analysis entries for a single CME, this flag would indicate which analysis is considered most accurate per measurement type.

CME Analysis M2M_CATALOG LE true Plane-of-sky NONE -25.0 754.0 C 10.0 2025-03-24T23:57Z Measurement made with running difference imagery from SOHO LASCO C2/C3 using SWPC_CAT. Plane-of-sky measurement chosen due to data gap in STEREO A COR2 and lack of certainty in source location. Not modeled Elizabeth Juelfs on 2025-03-24T22:45Z
