CME Note: Wide CME seen W and S in SOHO and STEREO A associated with long duration M1.6-class solar flare/filament eruption near S10W68. Faint shock presents as a full halo with preference towards the west. Around 2023-08-05T06:45Z, a dark filament near the western portion of the disk is seen lifting off, becoming a bright structure as it leaves the disk towards the west. A somewhat unclear arrival signature, affected by low quality solar wind data from both DSCOVR and ACE during this time period. Arrival signature: initial increase in B_total from 7.4 nT to 10.5 nT, followed by another increase to 13.6 nT at 11:54Z. The signature looks like a messy sheath arrival and it is possible that there is a flux rope/magnetic cloud at ~2023-08-08T01Z but this could be another CME arrival (LASSOS team). The current arrival may also have been observed at STEREO A around 2023-08-07T08:46Z. Alternatively, this could be the combined arrival of 2023-08-04T04:17Z and 2023-08-04T04:49Z CMEs.

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.
