CME Observed Time: 2023-02-24T20:36ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/23915/-1
CME Note: Partial halo CME seen mostly to the NW in SOHO LASCO and STEREO A COR2A coronagraphs. The CME is associated with an M3.7-class flare and subsequent eruption from AR3229. The flare induces a large nearby filament channel to break and lift off seen best in SDO/GOES 304, but also in SDO 193 and GOES-16 195. The flare and CME are also associated with a small enhancement in 10 MeV protons observed at GOES. The likely arrival of this CME (possibly a glancing blow) is first seen at 2023-02-26T18:43Z in DSCOVR data as a rapid increase in magnetic field from 10 nT to near 20 nT as well as a simultaneous increase in solar wind speed from 470 km/s to 540 km/s and density from 10 to 20 particles/cc.

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.
