CME Note: Wide CME visible to the west in SOHO LASCO C2/C3 and STEREO A COR2. The source is the M8.7 flare peaking at 2024-07-29T12:55Z from AR 3762 with associated dimming, EUV wave, and opening field lines best seen in SDO AIA 193. The eruption is also visible in STEREO A EUV imagery. Arrival signature characterized by an amplification of magnetic field components with Btotal increasing from 1nT at 2024-08-01T16:47Z to 12nT at 17:33Z. There is a subsequent minor increase in solar wind speed from around 400 km/s to ~460 km/s at 17:00Z with an increase observed in density starting around 16:00Z. This weak interplanetary shock may be associated with the combined arrival of CMEs 2024-07-29T02:00Z, 2024-07-29T02:12Z, and/or 2024-07-29T13:25Z.

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.
