Prediction for CME (2023-02-08T17:06:00-CME-001)CME Observed Time: 2023-02-08T17:06Z
CME Note: Very faint full halo CME seen best in SOHO C3 running difference imagery from 2023-02-08T17:00Z to 19:00Z and as northern and southern lobes in C3 white light imagery and NW/SW lobes in STEREO A COR2A imagery. May possibly be associated with an M1.6-class solar flare and subsequent eruption from AR3213 with dimming seen in SDO 193 and GOES-16 284 starting around 16:09Z. This analysis is fairly speculative.
CME was not detected at Earth.

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
