Prediction for CME (2026-01-01T19:36:00-CME-001)

CME Observed Time: 2026-01-01T19:36Z

CME Note: CME first seen to the NNE by SOHO LASCO C2 beginning at 2026-01-01T19:36Z, as well as by SOHO LASCO C3 and GOES CCOR-1 in later frames. This CME is currently not visible in STEREO A COR2 imagery due to a data gap which began at 2026-01-01T04:38Z. The source of this event is a C6.2 flare from AR 14324 (N24E01) seen in SDO AIA 131 peaking at 2026-01-01T17:59Z. A wide region of dimming and field line opening is also visible in SDO AIA 171, 193, 211 and GOES SUVI 284, followed by post eruptive arcades seen in SDO AIA 131 and 193. | Arrival Information: Characterized by a sharp amplification of magnetic field components (B_t: approx. 5.7nT to 9.5nT , B_x: approx. -2.6nT to -1.8nT , B_y: -4.6nT to -6.6nT , B_z: -1.5nT to -6.2nT) along with increases in temperature (approx. 52kK to 182kK), density (approx. 0.23 p/cc to 2.36 p/cc) and speed (approx. 425km/s to 502km/s). This IPS signature is likely associated with the arrival of CME: 2026-01-01T19:36Z.

CCMC 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.
