Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2026-02-04T14:20Z ( DSCOVR: PLASMAG )

All Detecting Spacecrafts:

DSCOVR: PLASMAG

ACE: SWEPAM

ACE: MAG

Activity ID: 2026-02-04T14:20:00-IPS-001 (version 1)
Quality of ICME Signature: -1 (unspecified)
Note: Characterized by an amplification of magnetic field components with Btotal increasing from 10nT at 2026-02-04T14:20Z to 22nT at 2026-02-04T14:24Z. Solar wind speeds increase from ~300 km/s at 2026-02-04T14:20Z to 400 km/s at 2026-02-04T14:25Z. A subsequent increase in temperature is observed from 36,000 K to 212,000 K, with an increase in density also observed around this time from 1 p/cc to 13 p/cc. This interplanetary shock is likely associated with the arrival of CME: 2026-02-02T00:48Z. This arrival signature is still developing and analysis is ongoing.
