Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2025-05-31T00:15Z ( GOES: CCOR-1 )
All Detecting Spacecrafts:
GOES: CCOR-1
SOHO: LASCO/C3
Activity ID: 2025-05-31T00:15:00-CME-001 (version 2)
Active Region Number: 14100
Note Keyword:
GAP: Data gap
HAL: Halo CME
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
OFL: Moving/Opening field lines
DIM: Dimming
EUVW: EUV Wave
Morphology Keyword:
OS: Other and Shock Candidate
Note: Full-halo CME first seen in GOES-19 CCOR-1. Also seen in SOHO LASCO C2/C3 after the beginning of a downlink period with data streaming in starting at about 2025-05-31T01:00Z. No STEREO A COR2 imagery was available in real time for this CME due to a data gap which began at 2025-05-30T19:09Z. The source is an M8.1 flare from AR 14100 (N12E12). A significant area of opening field lines and dimming can be seen from near AR 14100 (N12E12) in SDO AIA 193/171/131/304 and GOES SUVI 284/304 beginning at 2025-05-30T23:47Z, immediately after the flare. Dimming and field line movement extends along a nearby filament which spans across most of the Earth-facing disk, stretching from approximately N30E05 to S15W35, snaking through the entire NW quadrant of the Earth-facing disk in a shape resembling the number '3'. It appears that most of the filamentary material ejected is from the upper lobe of the '3', and departs from approximately N10W15.
