Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-03-22T15:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
Activity ID: 2025-03-22T15:48:00-CME-001 (version 1)
Note Keyword:
HAL: Halo CME
Source Signature Keyword:
OFL: Moving/Opening field lines
Morphology Keyword:
Note: This CME is faint but visible as a partial halo directed towards the southeast in SOHO LASCO C2/C3 imagery. It is observed as a faint far-sided halo in STEREO A COR2 imagery. The source is likely far-sided, and may be related to faint field line movement visible far beyond the southeast limb in GOES SUVI 284 imagery starting around 2025-03-22T14:35Z.

CME Analysis M2M_CATALOG SH true SWPC_CAT -147.0 -12.0 1190.0 O 45.0 2025-03-22T18:28Z SHOCK measurement based on the best fit between SOHO LASCO C2/C3 imagery and the one available frame of this event seen in STEREO A COR2 imagery, due to an ongoing campaign. This event is likely far-sided and the source location is unknown. The measured parameters may vary as a result. 1: Result 1 (5.5 AU)
OSIRIS-APEX = 2025-03-23T21:33Z
Juno = 2025-04-05T00:00Z
2: Result 2 (2.0 AU)

CME Analysis M2M_CATALOG LE true SWPC_CAT -147.0 -12.0 1084.0 O 20.0 2025-03-22T18:23Z BULK measurement using the same longitude as what was measured in the shock measurement. The measured parameters may vary greatly as the bulk portion of this event is difficult to distinguish in STEREO A COR2 imagery. Additionally, this event is likely far-sided so there is no source location to confirm the measured parameters. 1: Result 1 (2.0 AU)
OSIRIS-APEX = 2025-03-24T07:00Z
2: Result 2 (5.5 AU)
Juno = 2025-04-07T12:00Z
OSIRIS-APEX = 2025-03-24T07:00Z
