Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-06-03T07:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
SOHO: LASCO/C3
STEREO A: SECCHI/COR2
GOES: CCOR-1
Activity ID: 2025-06-03T07:48:00-CME-001 (version 3)
Source Location: N20E01
Note Keyword:
DPL: CME exhibits dimpled front
OFL: Outflowing material at the back of the CME
Source Signature Keyword:
PEA: Post eruption arcade
FIL: Filament eruption
DIM: Dimming
Morphology Keyword:
F: Flux Rope
Note: A slow CME to the northeast in SOHO LASCO C2/C3, GOES CCOR-1 and STEREO A COR2, seen more brightly in COR2A and appearing as a faint partial halo in CCOR-1. Its start time could possibly be even earlier, but the clear front is seen closer to 2025-06-03T07:48Z. Its source could be an eruption of a filament in the north/northeast, seen in SDO AIA 193/304 and EUVI A 195/304/284 starting at ~2025-06-03T01:21Z. Initial dimming and faint post-eruptive arcades are centered around ~(N20E01), but later the dimming is seen migrating/expanding eastwardly through the rest of the morning, and settling on a large circular area centered ~N35E15 by 2025-06-03T12:20Z.

CME Analysis M2M_CATALOG LE true SWPC_CAT -20.0 14.0 328.0 S 36.0 2025-06-03T18:09Z Analysis of the first closed loop front (not the initial dimpled/broken/fuzzy front) based on the best fit with two coronagraphs (SOHO LASCO and STEREO A COR2). This analysis is approximate, as longitude of the fit can vary from -17 to 27 degrees. 1: Result 1 (2.0 AU)
