Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-05T20:36Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-05-05T20:36:00-CME-001 (version 1)
Note Keyword:
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
GAP: Data gap
Source Signature Keyword:
Morphology Keyword:
J: Jet
Note: Faint narrow CME to the northeast in SOHO LASCO C2 and in several early timestamps of C3. The CME is fully covered by the nighttime data gap in STEREO A COR2 and is likely obscured by the pylon in GOES CCOR-1. No coronal signatures for this event have been found in EUV imagery.

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 63.0 641.0 C 10.0 2025-05-06T02:12Z The CME is fully covered by the nighttime data gap in STEREO A COR2 and is only seen in SOHO LASCO imagery; no source has been found for this event. Therefore only plane-of-sky measurement (with SOHO LASCO imagery) is possible. Not modeled Anna Chulaki on 2025-05-06T16:37Z
