CME Note: The CME visible N/NE in SOHO LASCO C2, C3 and STEREO A COR2 imagery. There is a more clear bulk portion that shows filamentary structures within it and then a more faint partial halo seen more clearly in difference imagery. The source is a filament eruption from the region NE of AR13216, there is also subsequent brightening, potential flaring from AR13216 during this eruption. From Tarik Salman, LASSOS team: Arrival is marked by the enhancement of the B field over the background, accompanied by a drop in proton density and the start of a low-density period. Temperature data seems to be sensitive. A significant data gap makes it difficult to analyze the nature of field rotations. However, the rotations might not be significant due to a possible flank crossing. Due to that, at L1, the flux rope is possibly not encountered.
CME Shock Arrival Time: 2023-02-13T17:02Z
Observed Geomagnetic Storm Parameters due to CME:
Max Kp: 5.33

Predicted Arrival Time: 2023-02-14T01:00Z (-12.0h, +9.0h)
Confidence that the CME will arrive: 40.0%
Predicted geomagnetic storm max Kp range due to CME: 2.0 - 6.0
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: 2023-02-11T04:18Z
Radial velocity (km/s): 1700
Longitude (deg): E012
Latitude (deg): N26
Half-angular width (deg): 27

Notes: Low confidence in fit, due to shock and other CMEs leading to difficult analysis. Glancing arrival possible - mainly shock, rather than ejecta.

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.
