CME Observed Time: 2023-04-21T18:12ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/24720/-1
CME Note: Halo CME visible in SOHO LASCO C2/C3 and STEREO A COR2 imagery. The source is a filament eruption starting around 2023-04-21T17:30Z visible in SDO AIA 131, 171, 193, 304, as well as STEREO A EUVI 195 and 304 imagery near the vicinity of Active Region 3283. An EUV wave is visible in SDO AIA 171 and 193 starting around 18:00Z, with an associated M1.7 flare peaking at 18:12Z. Post-eruptive dimming is visible in SDO AIA 193 starting around 18:15Z. Arrival of the shock of this CME at L1 is marked by an abrupt jump in total magnetic field to 27 nT and in solar wind speed from ~380 to over 500 km/s (with further increases to 34 nT and ~600 km/s respectively). There were several bouts of negative Bz, with the maximum negative value of -32 nT. The flux rope seems to arrive around 2023-04-24T01:19Z and is marked by smooth rotation of all three magnetic field components.

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.
