CME Note: [IN REVIEW] Halo CME visible in SOHO LASCO C2, C3, and STEREO A COR2 imagery. This halo is associated with the X2.2 class flare from AR13664 peaking at 2024-05-09T09:13Z. A clear EUV wave is visible in SDO/AIA 193 and 211 crossing towards the central meridian and towards the limb in the southwest. Post-eruptive arcades are present in SDO/AIA 193 and 131. Brightening is visible in SDO/AIA 304. Possible arrival signature is characterized by an initial sheath/compression of magnetic field components with Btotal reaching a maximum of 28nT. A subsequent increase in solar wind speed was observed from 643 km/s at 09:32Z to 900 km/s at 11:25Z. An increase in density was observed from ~2 N/cm^3 at 09:01Z to ~26 N/cm^3 at 09:22Z, with temperature exhibiting a sharp increase starting around 09:50Z. Due to the high solar wind speed observed with this arrival, it is possible this signature is associated with the arrival of CME: 2024-05-08T22:24Z and/or CME: 2024-05-09T09:24Z.

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.
