Prediction for CME (2023-01-20T13:38:00-CME-001)CME Observed Time: 2023-01-20T13:38Z
CME Note: Bright, wide CME with filamentary structure seen to the southwest in SOHO LASCO and STEREO A COR2 coronagraphs. Associated with a large-scale filament eruption whose filament at 2023-01-20T11:00Z was stretched from S42W25 northwest to about S30W70 (center point approximately S35W52). The eruption and post eruptive brightening is seen best in SDO 304 but also in SDO 193/171/211 occurring near 13:00Z. Arrival observed at Earth on 2023-01-23T02:59Z is believed to be more likely associated with CME: 2023-01-20T16:12Z, though its arrival is possibly associated with this CME.
CME was not detected at Earth.
Observed Geomagnetic Storm Parameters due to CME:
Predicted Arrival Time: 2023-01-23T12:00Z (-8.0h, +8.0h)
Confidence that the CME will arrive: 20.0%
Predicted geomagnetic storm max Kp range due to CME: 2.0 - 5.0

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
