Prediction for CME (2023-05-22T14:09:00-CME-001)CME Observed Time: 2023-05-22T14:09Z
CME Note: Faint CME seen to the southeast in coronagraph imagery that disappears before leaving the C2 field of view; it is associated with a M1.9-class flare, type II sweep, and erupting loop seen best in GOES 16/18 284 near S40E20.
CME was not detected at Earth.
Observed Geomagnetic Storm Parameters due to CME:
Predicted Arrival Time: 2023-05-25T20:00Z (-12.0h, +12.0h)
Confidence that the CME will arrive: 15.0%
Predicted geomagnetic storm max Kp range due to CME: 3.0 - 5.0
Prediction Method: Other (SIDC)
Prediction Method Note:
Message id="372", Event id="325" From SIDC URSIGRAM 30523: SIDC SOLAR BULLETIN 23 May 2023, 1237UT SIDC FORECAST ... Coronal mass ejections: A slow faint coronal mass ejection (CME) was first observed in the LASCO/C2 chronograph imagery after 14:00 UTC on May 22nd. The CME is related to the impulsive low M-class flaring from NOAA AR 3312 with an accompanying on disc dimming and a type II radio burst detected around 13:40 UTC. The bulk of the CME is expected to miss Earth, but a weak glancing blow could arrive late on May 25th. No other Earth-directed CMEs have been detected in the available coronagraph imagery.Lead Time: 55.25 hour(s)

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
