Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2025-12-31T13:20Z ( DSCOVR: PLASMAG )

All Detecting Spacecrafts:

DSCOVR: PLASMAG

ACE: SWEPAM

ACE: MAG

Activity ID: 2025-12-31T13:20:00-IPS-001 (version 3)
Quality of ICME Signature: 1 (lacks some signatures)
Note: Potential weak glancing blow CME signature at 2025-12-31T13:20Z characterized by an increase in B_total from ~4nT to ~11nT, separation of magnetic field components, an increase in solar wind speeds from ~400 km/s to ~540 km/s, temporary increases in solar wind temperature and density, followed by drop in density. This feature may be embedded within the start of a weak coronal hole high speed stream.
