CME Observed Time: 2023-01-11T17:00Z

CME Note: This is a large, bright and wide CME visible to the SE in SOHO LASCO C2/C3, and STEREO A COR2 imagery. The likely source is seen as clear moving/opening field lines beyond the SE limb in STEREO EUVI A 195 after 2023-01-11T16:35Z, followed by high rising post-eruptive arcades on the limb in EUVI A 195 an hour later. (Note: There also was an eruption in the SE on the Earth-facing disk seen in AIA 304 starting 2023-01-11T20:45Z (with a significant-area dimming south of the AR 3184(S13E41) seen in AIA 193) but this eruption was several hours later than the start of the CME and thus likely unrelated to it). CME was most likely backsided. This arrival is still being analyzed.
CME was not detected at Earth.

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.
