Prediction for CME (2023-08-18T19:48:00-CME-001)

CME Observed Time: 2023-08-18T19:48Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/26559/-1
CME Note: Bright CME seen to the NW in SOHO LASCO C2 and C3. There is a data gap in STEREO A COR2 imagery for most of this event, it is possibly seen in later COR2A difference imagery frames after the data gap ends at 2023-08-18T23:23Z. The source of this CME is a C3.7 class flare from AR13409 (~N21W41) peaking at 2023-08-18T19:30Z with associated brief dimming to the NW of the AR starting around 2023-08-18T19:24Z, best seen in SDO/AIA 193. There is also very quick moving/opening field lines around the same time in SDO/AIA 193 to the NW. There is no obvious arrival across all solar wind parameters.
CME was not detected at Earth.

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.

If you are looking for the official U.S. Government forecast for space weather, please go to NOAA's Space Weather Prediction Center (https://swpc.noaa.gov). This "Experimental Research Information" consists of preliminary NASA research products and should be interpreted and used accordingly.
