CME Observed Time: 2026-07-27T07:09Z
DONKI Link: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/47806/-1
CME Note: CME observed to the NE in STEREO A COR2 and faintly in GOES CCOR-1, not in SOHO LASCO C2/C3 due to a real-time downlink gap. The source is a heavily deflected filament eruption observed well in GOES SUVI 304, from a small filament spanning approx. N16E12 to N25W00 (centered N25E05) at 2026-07-27T03:13Z when it began to slowly lift off, more fully lifting off past 2026-07-27T05:00Z, clearly deflecting sharply NE in the field-of-view. Field line movement and brightening in GOES SUVI 171 and dimming in GOES SUVI 195 was also observed.
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.
