Activity ID: 2026-08-25T08:33:00-IPS-001 (version 2)
Quality of ICME Signature: 2 (clear signatures)
Note: Characterized by a jump in B_total from approximately ~5nT to ~10nT, B_z starting postive and rotating negative about +10nT to -5nT over the signature. An increase in temperature and density is observed alongside an increase in speed from ~500 km/s to ~600 km/s with the magnetic shock. This is likely the arrival of CME 2026-08-23T00:12Z.
