CME Scoreboard: Prediction Detail

Prediction for CME (2026-08-03T03:38:00-CME-001)

CME Observed Time: 2026-08-03T03:38Z
DONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/47939/-1
CME Note: CME observed best to the E in STEREO A COR2. Also observed faintly to the W in SOHO LASCO C2 until a downlink gap begins at 2026-08-03T05:00Z, and faintly to the W in GOES CCOR-1. The source may be gradual field line brightening/opening from AR 14501 (S07W43) lasting approximately 2026-08-03T00:00Z to 2026-08-03T04:00Z in SDO AIA 193/211, likely deflected northeastward with proximity to the large southern polar coronal hole seen facing STEREO A EUVI.
CME was not detected at Earth.
Observed Geomagnetic Storm Parameters due to CME:

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.
