Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2026-06-13T09:51Z ( ACE: MAG )

All Detecting Spacecrafts:

ACE: MAG

ACE: SWEPAM

SOLAR-1: MAG

SOLAR-1: SWiPS

Activity ID: 2026-06-13T09:51:00-IPS-001 (version 4)
Quality of ICME Signature: 1 (lacks some signatures)
Note: Arrival signature characterized by a sharp jump in B_total from ~5 nT to ~8 nT accompanied by a sharp increase in solar wind speed form ~550 km/s to ~630 km/s as well as an increase in temperature from ~135k K to ~364k K and an increase in density from ~5 p/cc to ~14 p/cc. Starting around 2026-06-13T13:44Z, the magnetic field components become more stable with time until about 20:00Z, potentially indicating the presence of one or more passing flux ropes. This event is most likely associated with the arrival of CME: 2026-06-11T00:36Z. Two other CMEs, CME: 2026-06-09T16:36Z and CME: 2026-06-09T21:36Z, were also anticipated to provide very weak glancing blows within this timeframe, but have more likely missed.
