Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG Location: Earth Event Time: 2026-07-04T12:00Z ( SOLAR-1: MAG ) Quality of ICME Signature: 2 (clear signatures) Note: Characterized by a reconfiguration of magnetic field components and other solar wind parameters beginning most clearly at 2026-07-04T12:00Z, following an enhancement from the previous interplanetary shock at 2026-07-03T11:17Z and CME arrival at 2026-07-03T18:45Z. At this start time, solar wind speeds jump from ~590 km/s to ~640 km/s and density rises from ~0.68p/cc to ~24.81p/cc. Starting at 2026-07-04T11:37Z a rise in temperature from ~65k Kelvin to ~441k Kelvin is observed. Starting around 2026-07-04T12:30Z, B_total temporarily drops from ~14nT to ~9.47nT, rising back to a peak 19.43nT by 2026-07-04T14:06Z. This third enhancement in the solar wind within this arrival signature starting at 2026-07-03T11:17Z is associated with the likely combined arrival of CMEs 2026-07-02T02:36Z and 2026-07-01T21:12Z.
