Activity ID: 2026-07-27T15:27:00-IPS-001 (version 2)
Quality of ICME Signature: 1 (lacks some signatures)
Note: Characterized by an amplification of magnetic field components with Btotal increasing from ~5nT at 2026-07-27T15:27Z to 7nT at 2026-07-27T15:30Z. A subsequent increase in speed is observed from ~360 km/s at 2026-07-27T15:28Z to ~420 km/s at 2026-07-27T16:45Z. Temperature increases around this time from ~30,000 K to ~81,500 K, with density increasing from ~5 p/cc at 2026-07-27T15:27Z to ~8 p/cc at 2026-07-27T15:46Z. This signature is likely associated with the arrival of CME: 2026-07-24T04:38Z.
