CME Observed Time: 2026-01-08T17:00ZDONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/43839/-1
CME Note: Bright partial halo CME to the S and SE in SOHO LASCO and GOES CCOR-1 coronagraphs, fully covered by the daily data gap in STEREO A COR2. Its source is a massive, very complex filament eruption S and E of Active Region 14334 (S19E03), potentially involving two erupting filaments (one directly south of this active region and another more to the east. This eruption starts after ~2026-01-08T16Z to the SE of disk center and is associated with the long-duration C5.6 flare in this active region peaking at 2026-01-08T17:30Z. It is seen in SDO AIA 304/193 as bright, extensive post-eruptive arcades, a large-area dimming, faint EUV wave and erupting filaments seen in 304. Arrival at L1 (analyzed in discussion with LASSOS team): Significant shock signature characterized by a sudden jump in B total from 5 to 19nT, with Bz quickly reaching -18nT and then staying negative for four hours. Accompanied by a sharp increase in the solar wind speed from 450 to 620 km/s. There is also a sudden increase in ion density from 5 to 20 p/cc and a simultaneous, more gradual, increase in ion temperature from 35 K to over 500 K. After 2026-01-10T23:30Z the signature changes to what is likely an arrival of the flux rope, with smooth rotation of components and Bz turning northward for over four hours. B total increases from 7 to over 15 nT and density drops. It is possible that the initial shock signature incorporates a glancing blow from another CME.

Coronal mass ejections: A partial halo coronal mass ejection (SIDC CME 622) was observed in LASCO/C2 coronagraph data starting at 17:00 UTC on January 8. The CME is directed primarily toward the southeast from Earth's perspective and is likely associated with a filament eruption in the southeast from SIDC Sunspot Group 722 (NOAA Active Region 4334) and a C5.6 flare (SIDC Flare 6614), peaking at 17:30 UTC on January 8, produced by SIDC Sunspot Group 722. The CME may have an Earth-directed component, with a predicted arrival time late on January 10 - early on January 11. ...Lead Time: 33.02 hour(s)

Rules of the Road: CCMC requests that users notify the CCMC, CME
model/technique developers and submitting forecasters/researchers before
performing event and validation studies with data from the CME Arrival
Time Scoreboard. It is recommended that such studies be performed with
the knowledge and collaboration of developers and submitting
forecasters/researchers.
