Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-17T23:12Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-17T23:12:00-CME-001 (version 1)
Note Keyword:
DPL: CME exhibits dimpled front
PRM: Prominence material (filamentary structures)
Source Signature Keyword:
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
F: Flux Rope
Note: Wide CME observed to the W in SOHO LASCO C2/C3, STEREO A COR2, and GOES CCOR-1. The source is a far-sided filament eruption likely from old AR 4109, observed as filament ejecta in SDO AIA 304 beginning around 2025-06-17T22:51Z and field line movement in SDO AIA 171/193.

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 108.0 10.0 423.0 S 30.0 2025-06-18T07:54Z Measurement made using best fit between SOHO LASCO C2/C3 and STEREO A COR2 imagery, as well as location of source seen in available UV imagery. Leading edge becomes diffuse abut halfway through the STEREO A COR2 field of view. 1: Result 1 (2.0 AU)

CME Analysis M2M_CATALOG LE false SWPC_CAT 107.0 5.0 351.0 S 29.0 2025-06-18T09:20Z PRELIMINARY measurement. Triangulation between SOHO LASCO C2 and STEREO A COR2. This CME front is very rough and dimpled, so this measurement tracks the leading edge movement with the width encompasing the entire bright bulk material. 1: Result 1 (2.0 AU)
Juice = 2025-06-21T01:00Z
