Prediction for CME (2024-02-28T17:48:00-CME-001)
CME Observed Time: 2024-02-28T17:48ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/29410/-1
CME Note: Bright CME visible in the NW of SOHO LASCO C2/C3 associated with a M1.5-class flare from AR 3590 (N19W59) starting at 2024-02-28T16:24Z. Dimming visible in SDO AIA 193, rising loops and post-eruptive arcades are visible in SDO AIA 171/193, and flare with long-lasting post-eruptive arcades visible in SDO AIA 94/131. Not seen in STEREO A COR2 due to a data gap from 2024-02-28T13:23Z to 2024-02-29T03:09Z. Arrival note: Characterized initially as a jump in Bt from around 3nT to 5nT, with more notable spikes in density, temperature, and speed from around 280 km/s to 320 km/s. Bt slowly rose to around 19nT by 2024-03-03T11:00Z with a long, sustained southward Bz reaching -16nT. The shock is not clearly observed (there is no abrupt increase in plasma data) and STA impact happens first and the sheath and its rotation are clearly seen and with a slight lag at L1, so the most likely candidates for this arrival are CME 2024-02-28T17:48Z and 2024-02-28T23:12:00-CME-001.

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.
