Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2026-01-04T20:41Z ( ACE: SWEPAM )

All Detecting Spacecrafts:

ACE: SWEPAM

ACE: MAG

DSCOVR: PLASMAG

Activity ID: 2026-01-04T20:41:00-IPS-001 (version 2)
Quality of ICME Signature: 1 (lacks some signatures)
Note: Characterized by a sharp amplification of magnetic field components (B_t: approx. 5.7nT to 9.5nT , B_x: approx. -2.6nT to -1.8nT , B_y: -4.6nT to -6.6nT , B_z: -1.5nT to -6.2nT) along with increases in temperature (approx. 52kK to 182kK), density (approx. 0.23 p/cc to 2.36 p/cc) and speed (approx. 425km/s to 502km/s). This IPS signature is likely associated with the arrival of CME: 2026-01-01T19:36Z.
