Prediction for CME (2023-08-05T07:12:00-CME-001)

CME Observed Time: 2023-08-05T07:12Z

CME Note: Wide CME seen W and S in SOHO and STEREO A associated with long duration M1.6-class solar flare/filament eruption near S10W68. Faint shock presents as a full halo with preference towards the west. Around 2023-08-05T06:45Z, a dark filament near the western portion of the disk is seen lifting off, becoming a bright structure as it leaves the disk towards the west. A somewhat unclear arrival signature, affected by low quality solar wind data from both DSCOVR and ACE during this time period. Arrival signature: initial increase in B_total from 7.4 nT to 10.5 nT, followed by another increase to 13.6 nT at 11:54Z. The signature looks like a messy sheath arrival and it is possible that there is a flux rope/magnetic cloud at ~2023-08-08T01Z but this could be another CME arrival (LASSOS team). The current arrival may also have been observed at STEREO A around 2023-08-07T08:46Z. Alternatively, this could be the combined arrival of 2023-08-04T04:17Z and 2023-08-04T04:49Z CMEs.

Predicted Arrival Time: 2023-08-07T18:00Z (-6.0h, +6.0h)
Confidence that the CME will arrive: 50.0%
Predicted geomagnetic storm max Kp range due to CME: 3.0 - 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)

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: 
Radial velocity (km/s): 1020
Longitude (deg): 047W
Latitude (deg):  10S
Half-angular width (deg): 47

Notes: Glancing impact most likely, but may also arrive with, or shortly after CME on 07 Aug to give increased enhancement.

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.
