Prediction for CME (2024-01-20T09:24:00-CME-001)

CME Observed Time: 2024-01-20T09:24Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/28649/-1
CME Note: Partial halo CME seen to the south/southeast in SOHO LASCO C2/C3 and STEREO A COR2. Source is a filament eruption on the Earth-facing disk stretching from S15E00 to S15E35, with liftoff starting around 2024-01-20T08:27Z. This CME overlaps with another filament eruption on the NE limb which resulted in CME:2024-01-20T09:36Z. | [PRELIMINARY] CME Arrival Note: potential combined arrival of this CME and the CME seen at 2024-01-21T00:36Z beginning around 16:00Z with B_total increase to ~14 nT. This arrival appears to be followed by a solar sector boundary crossing starting around 2024-01-23T19:30Z.
CME Shock Arrival Time: 2024-01-22T16:01Z
Observed Geomagnetic Storm Parameters due to CME:
----

Predicted Arrival Time: 2024-01-23T06:00Z (-9.0h, +7.0h)
Confidence that the CME will arrive: 70.0%
Predicted geomagnetic storm max Kp range due to CME: 5.0 - 7.0
Prediction Method: WSA-ENLIL + Cone (Met Office)
Prediction Method Note:

Met Office ENLIL settings.
ENLIL version: 2.7
Resolution: medium-res (512x60x180) (X1=0.1-1.7/uniform X2=30.-150./uniform X3=0.-360./uniform)

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.
