Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG Location: Earth Event Time: 2026-07-03T18:45Z ( SOLAR-1: MAG ) Quality of ICME Signature: 2 (clear signatures) Note: Characterized by an increase in B_total from ~10nT to a peak B_total 24.5nT at 2026-07-04T00:28Z, on top of an enhancement from the previous interplanetary shock at 2026-07-03T11:17Z. B_z starts largely northward but sharply dips and sustains southward direction starting around 2026-07-03T00:36Z, reaching a peak -19nT at 2026-07-04T04:16Z. Solar wind speeds further jump from ~460 km/s to ~600 km/s, reaching a peak ~630 km/s around 2026-07-04T03:15Z prior to the subsequent CME arrival at 2026-07-04T12:00Z. Density increases from ~6.1p/cc to ~40.38p/cc by 2026-07-04T00:49Z. Temperature jumps from ~436k Kelvin to ~1.29M Kelvin by 2026-07-03T20:10Z. This second enhancement in the solar wind within the arrival signature starting at 2026-07-03T11:17Z is most likely attributed to the early arrival of CME: 2026-07-01T12:12Z.
