CME Observed Time: 2022-12-30T16:53ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/23070/-1
CME Note: CME seen to the SW in STEREO Ahead along the SW streamer during a SOHO data gap. Likely associated with ejecta following an M1.4-class flare from AR13176. A distinct EUV wave is visible in GOES SUVI 195 starting around 2022-12-30T15:28Z to the S/SW of the eruption and continues to spread with some deflection to the south, likely due to a nearby coronal hole. There is also some dimming seen to the SW of the eruption that may have been caused by an earlier eruption starting around 2022-12-30T11:30Z which could be associated with a potential separate CME feature (bulk) in the white-light imagery just ahead of the wider measurable portion of this CME. Due to some uncertainty caused by the lack of SOHO imagery, the two CMEs are treated together here as one. The arrival is seen on 2023-01-03 when B_total initially increased from 3nT to 10nT and was accompanied by an increase in density and speed at the arrival of the sheath.

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.
