Prediction for CME (2021-08-28T07:00:00-CME-001)

CME Observed Time: 2021-08-28T07:00Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/17609/-1
CME Note: The source is a M4.7 class flare peaking at 2021-08-28T06:11Z from active region 12860 located at S28E00 at the time of the eruption. This eruption is visible in STEREO A EUVI 195 and SDO/AIA wavelengths. An EUV wave is visible in SDO/AIA 193, 171, and 211 starting around 2021-08-28T06:00Z, propagating northward, followed by a post-eruptive arcade starting around 2021-08-28T07:20Z. A dimming region is visible above the brightening active region during the EUV wave. Some plasma material is also visible lifting off during this eruption shortly after the flare peaks. Arrival characterized by slow magnetic field amplitude rise (reaching only 6.5 nT), accompanied by density/temperature rise, followed by field component rotation, density/tempurature drop, and speed rise. Followed by a SSBC at 2021-09-03T12:12Z, which obscures the later part of the ICME arrival signature.

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.
