Prediction for CME (2023-08-05T07:12:00-CME-001)CME Observed Time: 2023-08-05T07:12ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/26352/-1 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.
