Prediction for CME (2024-09-11T02:23:00-CME-001)
CME Observed Time: 2024-09-11T02:23ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/33323/-1
CME Note: CME first seen in the NE by STEREO A COR2. There is currently no SOHO LASCO imagery for this event due to a data gap from 11/02:36Z to 11/07:12Z. The source of this event is an M1.0 class flare peaking at 2024-09-10T23:50Z and subsequent eruption from AR 3814 (N16W03) as seen in SDO AIA 193, 211 and STEREO A EUVI 304. The flare peaked at 2024-09-10T23:50Z, however the eruption continued through approx. 11/01:30Z as seen in SDO AIA 304. Opening field lines, slight dimming and a possible EUV wave can be seen propagating towards the NE in SDO AIA 193, 211 and STEREO A EUVI 195. Due to the lack of SOHO data available to triangulate the source, there is some degree of uncertainty in the latitude and longitude of this CME. Characterized by an increase in magnetic field components from approx. 7nT to 9nT with an increase in density and a sustained period of southward field from 2024-09-13T17:45Z from 2024-09-13T21:30Z. There is no clear increase in solar wind speed or temperature.

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.
