Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2025-11-07T04:48Z ( ACE: MAG )

All Detecting Spacecrafts:

ACE: MAG

ACE: SWEPAM

DSCOVR: PLASMAG

Activity ID: 2025-11-07T04:48:00-IPS-001 (version 1)
Quality of ICME Signature: -1 (unspecified)
Note: Characterized by a sharp amplification of magnetic field components with Btotal increasing from 5nT at 2025-11-07T04:50Z to ~17nT at 2025-11-07T05:00Z. Solar wind speed observes an increase from ~670 km/s at 2025-11-07T04:48Z, which was previously elevated due to the 2025-11-06 coronal hole high speed stream, to around 850 km/s 2025-11-07T08:33Z. Density also exhibits an increase from 2 p/cc at 2025-11-07T04:48Z to 9 p/cc at 2025-11-07T05:25Z, with temperature increasing from 400,000 K at 2025-11-07T04:48Z to ~930,000 K at 2025-11-07T06:53Z. This signature is likely associated with the combined arrival of CME: 2025-11-04T22:53Z and CME: 2025-11-05T10:53Z.
