Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2025-11-16T01:32Z ( ACE: MAG )

All Detecting Spacecrafts:

ACE: MAG

ACE: SWEPAM

DSCOVR: PLASMAG

Activity ID: 2025-11-16T01:32:00-IPS-001 (version 2)
Quality of ICME Signature: 1 (lacks some signatures)
Note: Characterised by a sharp jump in solar wind speed from 550 km/s to initially 650 km/s and eventually (around 2025-11-16T05Z to 700 km/s), likely indicating a shock/sheath. Magnetic field also had two consecutive jumps paralleling the solar wind speed increases: initially from 4n to over 10 nT and then to 15.7 nT by 2025-11-16T05Z. Ion temperature has the same increases as the solar wind speed and magnetic field. Bz was mostly positive, but ater 2025-11-16T08Z there were prolonged periods of negative Bz. Flux rope likely starts after 2025-11-16T09:30Z (when there is a drop in temperature, density and solar wind speed and a smoother rotation).
