CME Note: Faint loop CME seen to the E in SOHO LASCO C2 and STEREO A COR2. This CME overlaps heavily with the large filament eruption CME:2025-04-13T08:00Z. Source is a bit uncertain, but a candidate source is dimming seen near AR 4060 (N09E30) spanning from N00 to N15 and E20 to E30, starting around 2025-04-13T07:00Z in SDO AIA 193. 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.
