Prediction for CME (2022-01-16T20:48:00-CME-001)CME Observed Time: 2022-01-16T20:48ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/18867/-1 CME Note: This CME is associated with a C2.6 flare from active region 12929 (N08W30). The eruption is characterized by opening field lines and dimming best seen in SDO AIA 193 starting around 2022-01-16T19:20Z. The eruption is also visible in the northwest in STEREO A EUVI 195 with the same source signatures. UPDATE: This arrival signature exhibits an increase B-tot from 5 to 9nT with a coinciding increase in density. A subsequent rotation can be seen in the B-field components corresponding with a decrease in temperature that is indicative of a flux rope passage. CME Shock Arrival Time: 2022-01-18T23:04Z Observed Geomagnetic Storm Parameters due to CME: Max Kp: 6.0 Predicted Arrival Time: 2022-01-20T00:00Z Confidence that the CME will arrive: 20.0% Predicted geomagnetic storm max Kp range due to CME: 5.0 - 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: 2.2 Please specify following CME input parameters. Time at 21.5Rs boundary: 2022-01-17T02:35Z Radial velocity (km/s): 562 Longitude (deg): W024 Latitude (deg): N10 Half-angular width (deg): 19 Notes: Re-analysis of CME spawned from long-period C2 flare from AR2929 in NW quadrant. Main bulk of ejecta angled above and ahead of Earth in orbit, but some evidence of concurrent emission to N and NE of ecliptic may make for some form of partial halo, most visible on Lasco C2. MOSWOC Enlil deterministic run is a very faint glancing blow, but significant minority of MOSWOC Enlil ensemble members have a stronger hit, mainly within UTC day of Thursday 20 January. Low confidence given uncertainty in attributing N and NE-heading portions of any ejecta, higher confidence in main NW-heading portion.
