Prediction for CME (2023-02-15T02:12:00-CME-001)CME Observed Time: 2023-02-15T02:12Z
CME Note: Faint partial halo CME seen in SOHO LASCO C2/C3. Not visible in STEREO A COR2 due to a data gap from 2023-02-14T14:23Z to 2023-02-15T09:23Z. This eruption is associated with a C5.6 flare from AR 13220 and an eruption best seen in SDO AIA 304 starting around 2023-02-15T01:00Z centered around S05E15. The eruption can also be seen with dimming in SDO AIA 193. This CME leading edge is asymmetrical and has a component directed towards the south/southeast first visible in SOHO LASCO C2 at 2023-02-15T02:48Z while the rest of the CME starting at 02:12Z is directed more eastward. This eruption may be 2 simultaneous eruptions in close proximity but it is not clear if there are separate CMEs.
CME was not detected at Earth.

Prediction Method: WSA-ENLIL + Cone (NOAA/SWPC)
Prediction Method Note:
Product: Forecast Discussion Issued: 2023 Feb 15 1230 UTC Prepared by the U.S. Dept. of Commerce, NOAA, Space Weather Prediction Center Solar Activity ... A partial halo CME was observed in C2 imagery beginning near 15/0200 UTC. This appears to be associated with a filament eruption near Region 3220 and an area of dimming in the area north of the region that can be seen in SDO/AIA 193 imagery. Initial analysis suggests the ejecta is very likely to impact Earth. Additional modeling is ongoing to determine the timing of arrival. ...Lead Time: 51.23 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
