CME Observed Time: 2023-07-14T19:10Z

CME Note: CME is faint and difficult to observe, seen as a partial halo to the S/SW in SOHO LASCO C2 and for few frames in STEREO A COR2 preceding data gap. The source is likely an eruption and subsequent C8.8 flare from AR 3370 (near S18E14) starting around 2023-07-14T18:35Z as seen in SDO AIA 131, 171, 193, 304 imagery. Noticeably deflected W. Arrival signature: Sharp increase in B-total from 7nT to 13nT. Sudden fluctuation in B-field components and increases in solar wind speed from ~350km/s to ~450km/s, in temperature and gradual increase in density. From Tarik Salman, LASSOS: definite shock arrival ~2023-07-16T18:35Z and another similar and more prominent feature in the plasma data around 2023-07-17T01:26Z (speed jump of 200 km/s) but nothing in the magnetic field. It is possible to have an admixture of HSS as well late on 2023-07-17.

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.
