CME Note: [PRELIMINARY] Partial halo CME to the NE in SOHO LASCO C2/C3 and STEREO A COR2. The source centered around N20E05. A C3.0 flare peaked at 2024-02-01T07:43Z, accompanied by dimming and post-eruptive arcades in STEREO A EUV 195 and SDO AIA 193, but eruption is partially obscured by an eclipse in SDO From 2024-02-01T06:42Z to 2024-02-01T07:51Z. Filamentary material seen lifting off in GOES SUVI 304, opening field lines are seen in SDO AIA 171, and post-eruptive arcades are best visible in SDO AIA 94. Possible arrival signature is unclear. The complex signature is characterized by gradual increases in Btotal (to 11nT) and solar wind speed (to 500 km/s), as well as rapid fluctuations of magnetic field components indicative of a high speed stream. It is possible that this signature includes a CME arrival, as it also encompasses a drop in temperature and density over 2024-02-05. The signature will be revisited once Level 1 solar wind data is available.

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.
