Prediction for CME (2026-05-27T22:37:00-CME-001)

CME Observed Time: 2026-05-27T22:37Z
DONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/46435/-1
CME Note: Faint SE partial halo CME in SOHO LASCO C2/C3 and GOES CCOR-1, and visible to the SE in STEREO A COR2 at 2026-05-28T01:38Z. The source of this event is likely very faint dimming and field line movement seen centered at approx. S20E20 as seen in SDO AIA 193, starting as early as around 2026-05-27T19:00Z.
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.
