Prediction for CME (2021-09-23T05:48:00-CME-001)

CME Observed Time: 2021-09-23T05:48Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/17810/-1
CME Note: CME SE in SOHO LASCO C2/C3 and SW in COR2A. Source: 2.8 class flare in AR 2871 with location S22E28 and eruption seen in AIA 193 and EUVI A 195 extending from AR 2871 NE and SW, with dimming and post-eruptive archades. The CME arrival at L1 is denoted by the increase in magnetic field (B total increase to above 10nT, magnetic field rotation (Bz stayed mostly positive, a clear flux rope is observed) and decrease in ion temperature.
CME Shock Arrival Time: 2021-09-26T23:00Z
Observed Geomagnetic Storm Parameters due to CME:
Max Kp: 3.0

Predicted Arrival Time: 2021-09-27T15:00Z
Predicted geomagnetic storm max Kp range due to CME: 3.0 - 2.0
Prediction Method: WSA-ENLIL + Cone (NASA M2M)
Prediction Method Note:
NASA GSFC SWRC ENLIL settings:
ENLIL version: 2.7
Resolution: low2 (256x30x90)
Ambient settings: a3b1f
WSA version: 2.2
(Enlil 2.7 w/res:low2 ambient:a3b1f, WSA2.2)

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.
