Prediction for CME (2023-10-16T12:09:00-CME-001)
CME Observed Time: 2023-10-16T12:09ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/27320/-1
CME Note: Bright CME seen to the NE in SOHO LASCO C2/C3 and STEREO A COR2. Source is C7.5 class flare starting at 2023-10-16T10:31Z and associated eruption. The flare can be best seen in SDO AIA 131/193, opening field lines are visible in SDO AIA 171/193, and dimming and post eruptive loops are also seen in SDO AIA 193. Arrival Signature: Characterized by a weak amplification of magnetic field components with Btotal reaching 10nT at 2023-10-20T12:38Z. Subsequent increases were observed in density and temperature. This was followed by a rotation in magnetic field components during which an extended period of negative Bz was observed from around 2023-10-20T17:30Z to 2023-10-21T08:00Z. This arrival signature may be reflective of a weak arrival/glancing blow from CME: 2023-10-16T12:09Z.

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.
