Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-15T03:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-05-15T03:48:00-CME-001 (version 1)
Source Location: S34E80
Note Keyword:
Faint: Faint event; may affect type assignment
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
OFL: Moving/Opening field lines
BR: Brightening
Morphology Keyword:
O: Other
Note: Diffuse, fast CME front observed to the southeast in SOHO LASCO C2/C3, STEREO A COR2, and GOES CCOR-1. The source is observed approximately around S34E80, as a small filament eruption in SDO AIA 304 and field line movement/small post-eruptive arcade in SDO AIA 171/193, beginning around 2025-05-15T02:45Z.

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 -75.0 -50.0 953.0 C 11.0 2025-05-15T07:28Z Triangulated measurement between SOHO LASCO C2 and STEREO A COR2. The LASCO C3 pylon obscures CME visiblity in the running difference imagery and it cannot be resolved there. Not modeled Tony Iampietro on 2025-05-15T15:50Z
