Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: STEREO A
Event Time: 2025-11-26T18:48Z ( STEREO A: IMPACT )

All Detecting Spacecrafts:

STEREO A: IMPACT

STEREO A: PLASTIC

Activity ID: 2025-11-26T18:48:00-IPS-001 (version 2)
Quality of ICME Signature: 1 (lacks some signatures)
Note: Characterized by a rotation and minor amplification of magnetic field components with Btotal increasing from ~7nT at 2025-11-26T18:48Z to 10nT at 2025-11-27T04:21Z. A minor increase in density is observed from 10 p/cc to ~16 p/cc around 2025-11-27T00:00Z, with no noticeable increase in speed or temperature. This signature may be associated with the glancing blow arrival of CME: 2025-11-23T23:30Z and/or CME: 2025-11-23T23:45Z.
