Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-04-01T18:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-04-01T18:24:00-CME-001 (version 1)

Note: This event is visible to the east in SOHO LASCO C2/C3 imagery. It is not observed in STEREO A COR2 due to a data gap starting at 2025-04-01T17:53Z. The source is likely far-sided as there are no source signatures on the Earth-facing disk at the time of this event.

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 20.0 662.0 C 45.0 2025-04-01T23:35Z A plane-of-sky measurement was made using a longitude of -90 degrees due to the far-sided and therefore unknown source location. Additionally, due to a data gap in STEREO A COR2 at the time of this event, a triangulated measurement was not available to confirm the measured parameters.
