Prediction for CME (2026-03-30T03:24:00-CME-001)

CME Observed Time: 2026-03-30T03:24Z
DONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/45395/-1
CME Note: Large partial-halo CME visible to the SE in SOHO LASCO C2/C3, GOES CCOR-1, and STEREO A COR2 imagery. The source is an X1.4 flare from Active Region 14405 (S27E45) peaking at 2026-03-30T03:19Z. The source is associated with brightening, dimming, moving/opening field lines, and EUV wave as seen in GOES SUVI 195, 304, 284, 131, 094, and 171 starting around 2026-03-30T02:56Z.

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.
