Prediction for CME (2023-01-14T21:36:00-CME-001)

CME Observed Time: 2023-01-14T21:36Z
CME Note: This CME is visible as a partial halo to the W/SW in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is an eruption and subsequent M4.6 flare from AR 3182 seen in SDO AIA 131, 171, 193, 304 imagery starting around 2023-01-14T20:35Z. An opening of field lines is visible in SDO AIA 171 at 20:50Z and post eruptive loops start to form in SDO AIA 193 around 22:30Z. Eruption is also visible in STEREO A EUVI 195 and 304 imagery. Arrival is characterized by a sharp increase in magnetic field components with B total reaching 15 nT. Solar wind speeds increased from 387 km/s at 2023-01-17T20:53Z to 488 km/s at 2023-01-18T02:08Z. Additional increases in density and temperature. Signature is still developing and analysis is ongoing. This arrival may also be associated with CME: 2023-01-15T03:48Z.
CME Shock Arrival Time: 2023-01-17T21:10Z

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.
