Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2025-07-03T05:38Z ( ACE: MAG )

All Detecting Spacecrafts:

ACE: MAG

ACE: SWEPAM

DSCOVR: PLASMAG

Activity ID: 2025-07-03T05:38:00-IPS-001 (version 2)
Quality of ICME Signature: 2 (clear signatures)
Note: Characterized by a sharp increase in magnetic field components (B_t: approx. 4.2nT to 13.2nT , B_x: approx. 6.7nT to -8.1nT , B_y: approx. 4.8nT to -4.9nT , B_z: approx. -7.6nT to 9.7nT) along with enhancement in speed (approx. 342km/s to 407km/s), temperature (approx. 12kK to 44kK) and density (approx. 7p/cc to 33p/cc). This signature also displays separation in magnetic field components, indicating the possible passage of a flux rope.
