Prediction for CME (2023-01-14T21:36:00-CME-001)

CME Observed Time: 2023-01-14T21:36Z
iSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/23318/-1
CME Note: This CME is visible as a partial halo to the W/SW in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is an eruption and subsequent M4.6 flare from AR 3182 seen in SDO AIA 131, 171, 193, 304 imagery starting around 2023-01-14T20:35Z. An opening of field lines is visible in SDO AIA 171 at 20:50Z and post eruptive loops start to form in SDO AIA 193 around 22:30Z. Eruption is also visible in STEREO A EUVI 195 and 304 imagery. Arrival is characterized by a sharp increase in magnetic field components with B total reaching 15 nT. Solar wind speeds increased from 387 km/s at 2023-01-17T20:53Z to 488 km/s at 2023-01-18T02:08Z. Additional increases in density and temperature. Signature is still developing and analysis is ongoing. This arrival may also be associated with CME: 2023-01-15T03:48Z.
CME Shock Arrival Time: 2023-01-17T21:10Z
Observed Geomagnetic Storm Parameters due to CME:
----

Predicted Arrival Time: 2023-01-19T03:00Z
Predicted geomagnetic storm max Kp range due to CME: 4.0 - 5.0
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)
Ambient settings: a3b2-sa1
WSA version: 4.5
GONG: mrzqs
Note that this arrival time forecast is based on the simulation but is then adjusted by a human-in-the-loop.

Please specify following CME input parameters.
Time at 21.5Rs boundary: 2023-01-15T09:00Z
Radial velocity (km/s): 400
Longitude (deg): 046W
Latitude (deg): 30S
Half-angular width (deg): 53

Notes: "Clear lift off from region of AR3182 as a result of two concurrent flares [treated as one event here for modelling]. Liftoff appears on AIA94 at around time indicated. Clear fit on both C3, C2 and STEREO A. Good confident fit". Edit - MTL - reanalysis did not sig alter above save 27W and 341km/s details, prob worse fit compared with emission loc, and RPS's wholly preferred.

Lead Time: 55.67 hour(s)
Difference: -29.83 hour(s)

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.
