Coronal Mass Ejection
Catalog: M2M_CATALOG
Start Time: 2026-02-02T00:48Z ( SOHO: LASCO/C2 )
All Detecting Spacecrafts:
SOHO: LASCO/C2
GOES: CCOR-1
Activity ID: 2026-02-02T00:48:00-CME-001 (version 5)
Source Location: N13E35
Active Region Number: 14366
Note Keyword:
DFL: Likely deflection of the event within the FOV
Faint: Faint event; may affect type assignment
GAP: Data gap
HAL: Halo CME
OFL: Outflowing material at the back of the CME
OVR: Event partially overlaps with another CME
CHP: CME - Coronal Hole Proximity
Source Signature Keyword:
FLR: Flare
FIL: Filament eruption
OFL: Moving/Opening field lines
Morphology Keyword:
FS: Flux Rope and Shock Candidate
Note: Complex CME consisting of multiple overlapping fronts, the first of which is first seen to the NE in SOHO LASCO C2 beginning at 2026-02-02T00:48Z, as well as in GOES CCOR-1 in later frames. The start of this event is covered in STEREO A COR2 by a data gap which began at 2026-02-01T14:53Z and ended at 2026-02-02T03:23Z, but after the data gap at least one lobe of this CME is clearly seen to the ENE in STEREO A COR2 in multiple timestamps. The source of this event is an X8.1 flare from Active Region 14366 (N13E35) that peaked at 2026-02-01T23:57Z and possibly also the following X2.8 flare from the same AR peaking at 2026-02-02T00:36Z. The flares are visible in SDO AIA and GOES SUVI 131. Two eruptions of filament ejecta are also seen in SDO AIA and GOES SUVI 304 in association with these flares, the earlier ejecta more northwardly directed and seemingly deflecting towards the west, and the ejecta after the second flare which is not as northward as the initial one.

Final, approximate and speculative analysis based on the fitting with all three coronagraphs (SOHO LASCO C2/C3, STEREO A COR2 and GOES CCOR-1) once STEREO A COR2 imagery became available after the end of the daily data gap in STEREO A. This analysis leaves out the earliest, more northward, faint front seen in SOHO C2 and CCOR-1 as the likely corresponding very faint front in the first couple of available STEREO A COR2 after the data gap is very unclear/obscured by brighter following front. The CME is treated as one event in this analysis. The fitting indicates a likely significant deflection westwards from the source location (location of the X-class flares from Active Region 14366), possibly due to the effect of the coronal hole to the NE of the Active Region location. Analysis is complicated by the asymmetrical shape of the CME in STEREO A COR2, the fact that the start of the CME is obscured by the data gap in STEREO and the difficulty separating multiple overlapping fronts in SOHO and CCOR-1. |
