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 1)
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. This filament is also located directly next to, and runs parallel to, the SWPC-numbered Coronal Hole 52.
