Prediction for CME (2023-09-16T09:12:00-CME-001)
CME Observed Time: 2023-09-16T09:12ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/26949/-1
CME Note: Wide, complex, difficult to analyze CME with primary directionality (bulk) to the southwest in SOHO and STEREO A coronagraphs but containing features also seen to the west, south, and southeast along a discontinuous front. Associated with a large-scale filament eruption taking place on the Earth-facing disk from 2023-09-16T07:00Z to 09:00Z seen best in SDO/GOES 304; filament extends from N30W00 southwest through N10W30 with a minor, more narrow segment extending back east from N10W30 back towards S03W05. Arrival signature: Sudden sharp jump in solar wind parameters with B total reaching 21 nT and speed increasing above 550 km/s. May be indicative of additional coronal hole high speed stream influences (Tarik Salman, LASSOS team) from coronal hole at central meridian on 2023-09-15. Less likely but possible that this is a combined arrival of this CME and the 2023-09-14T23:12Z CME.

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.
