Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-05T23:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-05-05T23:36:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
GAP: Data gap
Source Signature Keyword:
Morphology Keyword:
JS: Jet and Shock Candidate
Note: A narrowish CME to the northeast in SOHO coronagraph, with a thiner bulk and a possibly slightly wider shock. No clear source has been found for this CME. There is a very minor filament swirling behind/near the NE limb that is seen moving in SDO AIA 171 and GOES SUVI 304 after 2025-05-05T21:20Z, however it is not clear whether the filament eventually leaves the sun.

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 63.0 774.0 C 11.0 2025-05-06T03:55Z The CME is likely fully covered by a nighttime data gap in STEREO A COR2 coronagraph and is only seen in SOHO LASCO C2 and C3 imagery. No clear source has been found for this event in EUV imagery. Therefore, only plane-of-sky analysis is possible. Not modeled Anna Chulaki on 2025-05-06T17:04Z
