CME Note: This CME is visible to the NE in SOHO LASCO C2/C3 and STEREO A COR2 coronagraph imagery. The source is likely the large dimming region centered around N25E25 which begins to dim around 2023-11-02T03:00Z as seen in SDO AIA 131, 171, 193, 304 imagery. Faint field line movement is visible above the eruption in SDO AIA 171 and 193 imagery, with post eruptive loops starting to form around 2023-11-02T04:30Z. ICME arrival signature is characterized by a sharp jump in magnetic field from already elevated 14 nT (after arrival a day before) to 25 nT, then gradually increasing to 34 nT, accompanied by rapid rotations of all three magnetic field components and by a jump in solar wind speed from 320 km/s to 430 km/s. There is a corresponding increase in ion density and temperature. Further analysis of this arrival signature in consultation with Lan Jian (NASA/GSFC) can be found in DONKI: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/IPS/27602/-1

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.
