Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-09-21T21:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-09-21T21:36:00-CME-001 (version 2)
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
Morphology Keyword:
JS: Jet and Shock Candidate
Note: A relatively bright jet-like CME seen to the ESE in SOHO LASCO and GOES CCOR-1 coronagraph and covered by the data gap in STEREO A COR2. No clear source has been found, however there is some activity on the E limb as seen in GOES SUVI 304.

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. This is a helpful flag if you would like to download only one most accurate CME analysis per CME per Measurement Type

CME Analysis M2M_CATALOG LE true Plane-of-sky NONE -10.0 762.0 C 16.0 2025-09-22T02:18Z The CME is covered by a data gap in STEREO A COR2, so only LASCO and GOES CCOR-1 imagery is available for it. No clear source has been found for this event. Only plane-of-sky analysis is possible. Not modeled Anna Chulaki on 2025-09-22T00:50Z
