Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: STEREO A
Event Time: 2026-08-22T01:24Z ( STEREO A: IMPACT )

All Detecting Spacecrafts:

STEREO A: IMPACT

STEREO A: PLASTIC

Activity ID: 2026-08-22T01:24:00-IPS-001 (version 3)
Quality of ICME Signature: 1 (lacks some signatures)
Note: Characterized by an amplification of magnetic field components with Btotal increasing from ~5nT at 2026-08-22T01:24Z to ~19nT at 2026-08-22T12:25Z. A minor increase in solar wind speed is observed around this time, increasing from ~370 to ~425 km/s. An increase in density from ~1 p/cc to ~10 p/cc is also observed. This signature may be associated with the arrival of CME: 026-08-18T14:45Z.
