CME Note: Faint, wide CME to SW in SOHO LASCO C2 imagery during STEREO A data gap and campaign with limited imagery. Likely associated with a broad area of coronal restructuring, coronal dimming, destabilization, and filament eruptions seen in SDO 193, 304 starting ~2023-03-20T01:53Z between S10 to S30, W05 to W30. Arrival may be associated with CME 2023-03-20T14:42Z. From Tarik Mohammad, LASSOS: start of sheath is ~2023-03-23T05Z - enhancements in total magnetic field/density. Background solar wind is quite different from normal levels with higher density (normal density around 5/cc) and speed (normal speed around 350-400 km/s). This can be a reason there is no shock. Start of the magnetic flux rope ~13:30Z coincides with enhancement in total field and drop in density. 2023-03-24T06:50Z is the possible end time based on an increase in temperature beyond this point and the field components becoming less coherent.

CCMC 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.
