Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-24T07:48Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
Activity ID: 2025-05-24T07:48:00-CME-001 (version 2)
Note Keyword:
DPL: CME exhibits dimpled front
Faint: Faint event; may affect type assignment
FF: Event fails/disappears before exiting COR2
HAL: Halo CME
Source Signature Keyword:
Morphology Keyword:
LS: Loop and Shock Candidate
Note: Very faint slow CME, a partial halo in SOHO LASCO C2, with a messy front consisting of multiple consecutive faint unevenly shaped fronts, seen extremely faintly to the northeast in SOHO LASCO and a bit more clearly to the northwest in STEREO A COR2. Not clearly visible in GOES CCOR-1. To satisfy this constraint - NE in LASCO, NW in STEREO - its longitude has to be between -155 and -175 degrees, so likely this is a very far-sided event. No clear source for it was 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 |

Approximate analysis based on the fit with two coronagraphs (SOHO LASCO and STEREO A COR2) and supported by the range of possible longitudes (based on the CME appearing northeast in LASCO and northwest in STEREO A). This analysis is based on the clearer second front directly following a messier first front of the CME, as they appear in both coronagraphs. |
