CME Note: This CME is visible as a partial halo to the west in SOHO LASCO C2/C3 and STEREO A COR2 coronagraph imagery. The source is an M8.2 flare and eruption from Active Region 13768 (S15W80) starting around 2024-08-01T07:00Z as seen in GOES SUVI 131, 171, 195, 284, 304 imagery. A wide opening of field lines is visible in GOES SUVI 171, 195, and 284 imagery at this time as well. Arrival: there is a clear ICME arrival signatures with a shock (according to analysis by the LASSOS team (Carlos Perez Alanis). During the shock B total reaches 19.5 nT and density gets increased to 20p/cc, followed by a period of significant negative Bz reaching -17nT. This signature of ICME shock is preceded by a less clear disturbance in the magnetic field at L1 with Btotal increasing from 8nT at 2024-08-04T04:48Z to 15nT at 06:11Z followed by a protracted period of negative Bz.

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.
