Note: CME first seen to the NE by SOHO LASCO C2 beginning at 2026-02-02T00:48Z, as well as by GOES CCOR-1 in later frames. This event is not visible in STEREO A COR2 due to a data gap which began at 2026-02-01T14:53Z. The source of this event is an X8.1 flare from Active Region 14366 (N13E35) that peaked at 2026-02-01T23:57Z. This flare is visible in SDO AIA and GOES SUVI 131. A large amount of filament ejecta is also seen in SDO AIA and GOES SUVI 304 in association with this flare, however it appear that a majority of this ejecta gets reabsorbed and does not make it off the solar disk.

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. |

Preliminary measurement with one-coronagraph analysis method, using early GOES CCOR-1 frames before SOHO LASCO and STEREO A COR2 imagery became available for this event, based on the approximate source location (X8 flare). |
