Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: Earth
Event Time: 2025-11-07T21:54Z ( ACE: MAG )

All Detecting Spacecrafts:

ACE: MAG

ACE: SWEPAM

Activity ID: 2025-11-07T21:54:00-IPS-001 (version 2)
Quality of ICME Signature: 1 (lacks some signatures)
Note: This signature is characterized by a small, short-duration increase in B_total from ~9 nT to ~12 nT that was associated with an flip in B_z orientation to predominantly southward, leading to a moderate geomagnetic storm between 2025-11-08T00:00Z and 03:00Z. The flip in B_z was accompanied by a phi angle flip and minor decreases in speed and density. This signature may be associated with the arrival of CME: 2025-11-05T22:23Z.
