Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-15T20:24Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-05-15T20:24:00-CME-001 (version 1)
Source Location: N15E45
Active Region Number: 14087
Note Keyword:
Source Signature Keyword:
FIL: Filament eruption
Morphology Keyword:
Note: CME first seen to the NE in SOHO LASCO C2 starting at 2025-05-15T20:24Z. CME is also visible to the NE in SOHO LASCO C3 and GOES CCOR-1. Also faintly visible for a single frame in STEREO A COR2. The source of this CME is possibly the more southern portion of some ejecta from a small filament eruption from AR 14087 (N14E40-50) best seen in SDO AIA 193 starting around 2025-05-15T18:30Z.

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 SWPC_CAT -45.0 29.0 818.0 C 17.0 2025-05-16T00:29Z This measurement is approximate due to lack of available triangulation. The only STEREO A COR2 frame in which this CME is visible is too faint to be usable for measurement. The source location is based on a visible on-disk source. 1: Result 1 (2.0 AU)
