Prediction for CME (2025-04-13T07:48:00-CME-001)
CME Observed Time: 2025-04-13T07:48ZiSWAS Layout URL: https://kauai.ccmc.gsfc.nasa.gov/DONKI/view/CME/38364/-1
CME Note: Faint and wide loop CME seen to the W in SOHO LASCO C2/C3 and as an extremely faint halo in STEREO A COR2. Source is a portion of filamentary material seen twisting as it lifts off at S20W30, which is the western-most side of the large filament eruption seen occurring around 2024-04-13T07:00Z. Liftoff of filamentary material is seen in SDO AIA 304 at 2024-04-13T07:10Z and dimming is seen in SDO AIA 193 at 2024-04-13T07:46Z, both from S20W30. The arrival signature is characterized by an amplification of magnetic field components with Btotal increasing from 6nT at 2025-04-15T16:36Z to 17nT at 16:38Z and 27 nT by 18:24Z. Two subsequent increases in solar wind speed is observed, increasing from 400 km/s at 2025-04-15T16:36Z to ~480 km/s at 16:37Z and later an increase from 475 km/s to 600 km/s starting at 19:40Z, with density increasing to 35 p/cc at this time as well. This signature is likely associated with the arrival of CME: 2025-04-13T08:00Z and CME: 2025-04-13T08:12Z, with possible influence from the arrival of CME: 2025-04-12T00:48Z, CME: 2025-04-13T00:12Z and CME: 2025-04-13T07:48Z. Magnetic field components become more stable over time after 2025-04-16T02:00Z and by 2025-04-16T10:00Z become very smooth with B_z oriented in the negative sector.

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.
