CME Note: Large complex-shaped (possibly partial halo) to the north. Source is likely the eruption of a very long filament stretching from N42E15 to N01W60 seen in AIA 193/304/131. The filament is centered very approximately around N30W30. The eruption was likely associated with the corresponding long duration C3.2-class flare peaking at 2023-11-03T06:17Z. Arrival signature: a sharp temporary jump in total magnetic field to 44 nT at 2023-11-05T11:45Z, up from the already elevated 20 nT after CME arrival four hours prior) accompanied by a jump in solar wind speed from 400 to 520 km/s; ion density remains high after the previous arrival in the morning. The arrival is followed by a bout of negative Bz with values close to -20 nT. 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/27611/-1

CCMC 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.
