Activity ID: 2026-09-17T01:24:00-IPS-001 (version 1)
Quality of ICME Signature: -1 (unspecified)
Note: Characterized by a minor amplification of magnetic field components with Btotal increasing from 5nT at 2026-09-17T01:24Z to 7nT at 2026-09-17T01:30Z. Solar wind speed increases from 476 km/s at 2026-09-17T01:24Z to 580 km/s at 2026-09-17T02:30Z. Additional increases in density, up to 10 p/cc, and temperature, up to 200,000 K, are observed at this time as well. This signature is likely associated with the arrival of CME: 2026-09-13T21:12Z and/or CME: 2026-09-14T11:08Z.
