Prediction for CME (2024-03-23T01:25:00-CME-001)
CME Observed Time: 2024-03-23T01:25ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/29715/-1
CME Note: Bright partial halo CME first seen to the north in SOHO LASCO C2 (appearing a few timestamps before the second northern front of 2024-03-23T01:48Z CME and earlier than the faint full halo to the SW). The CME is associated with the X1.1-class flare from Active Region 3614 centered ~N25E07 and with associated eruption seen as EUV wave in SDO AIA 193, and as a NE-SW oriented large area of dimming/post eruptive arcades centered ~around Active Region 3614. X-class flare was accompanied by/contributed to by concurrent flare from Active Region 3615 (S14E15). Combined arrival of this CME with CME: 2024-03-23T01:48Z was detected at L1 by DSCOVR and ACE at 2024-03-24T14:10Z. The arrival signature is characterized by sharp increase in B-total from 6nT to 26nT, reaching 33nT and by a jump in solar wind speed from about 550 km/s to 851 km/s, with a peak of 880 km/s and an increase in density and temperature seen at ~14:10Z.

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.
