CME Note: Partial halo seen directed towards the NW in all coronagraphs. Source is a C2.8 flare from AR 3514 which peaked at 2023-12-12T22:55Z, best seen in SDO AIA 131, and an associated dimming region starting at 2023-12-12T22:30Z best observed in SDO AIA 193/211. The dimming regions spans approximately W12->W26 and N11->S10, with the most dimming occurring centered around N06W19. A double ribbon flare/surface brightening is observed in this same region in SDO AIA 304, along with a small post-eruptive arcade that begins at the same time as the eruption. Clear arrival signature: A clear shock signature with a sharp increase in B total to initially 15nT and eventually to over 23nT, with rapid fluctuations of all magnetic field components. This is accompanied by a jump in solar wind speed at first from under 300 to 400 km/s, further increasing to just under 550 km/s and a sharp increase in ion density and temperature. There is also a matching arrival at STEREO A.

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.
