Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-23T16:53Z ( STEREO A: SECCHI/COR2 )
All Detecting Spacecrafts:
STEREO A: SECCHI/COR2
SOHO: LASCO/C2
SOHO: LASCO/C3
GOES: CCOR-1
Activity ID: 2025-05-23T16:53:00-CME-001 (version 1)
Note Keyword:
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Bright CME to the west in STEREO A COR2 imagery associated with a faint shock more easily seen as a halo in SOHO LASCO C2, C3, and GOES CCOR-1 imagery. The source is a far-sided filament eruption starting around 2025-05-23T16:45Z as seen in STEREO A EUVI 304 and briefly visible to the S/SW in GOES SUVI 304 starting around 2025-05-23T18:29Z and SDO/AIA 171 around 2025-05-23T17:23Z.

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 |

Measurement based on the BULK of the CME. Parameters are based on best fit relying more heavily on STEREO A COR2 imagery to differentiate the bulk and shock features. |

Measurement of faint SHOCK feature. Parameters based on best fit in SOHO LASCO C3 and STEREO A COR2 imagery. A portion of the shock front to the NW from SOHO LASCO C3's field-of-view was excluded from this fit due to measurement technique limitations. |
1: Result 1 (2.0 AU)
BepiColombo = 2025-05-24T05:12Z
