Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: STEREO A
Event Time: 2026-09-08T04:28Z ( STEREO A: IMPACT )

All Detecting Spacecrafts:

STEREO A: IMPACT

STEREO A: PLASTIC

Activity ID: 2026-09-08T04:28:00-IPS-001 (version 1)
Quality of ICME Signature: -1 (unspecified)
Note: Characterized by an amplification of magnetic field components with Btotal increasing from ~6nT at 2026-09-08T04:36Z to ~19nT at 2026-09-08T07:51Z. Velocity data is sparse in real-time, but appears to increase from ~400 km/s to ~800 km/s. Density data is also sparse but appears to increase from <1 p/cc to ~5 p/cc. This signature is likely associated with the arrival of CME: 2026-09-05T15:36Z.
