Interplanetary Shock (or CME Arrival)
Catalog: M2M_CATALOG
Location: STEREO A
Event Time: 2025-08-08T23:00Z ( STEREO A: IMPACT )

All Detecting Spacecrafts:

STEREO A: IMPACT

STEREO A: PLASTIC

Activity ID: 2025-08-08T23:00:00-IPS-001 (version 1)
Quality of ICME Signature: -1 (unspecified)
Note: Characterized by a sharp enhancement in magnetic field components (Bt: approx. 5nT to 10nT , Bx: approx. -5nT to -7nT , By: approx. 5nT to 05nT , Bz: approx. -1nT to 7nT) followed by a secondary fluctuation (Bt reaching 12nT, Bx reaching -10nT, By reaching 10nT and Bz reaching -10nT) beginning at approx. 2025-08-09T04:00Z. Velocity, temperature and density data is too sparse to identify notable enhancements. This signature may be the combined arrival of CME: 2025-08-05T16:48Z (modeled to arrive at 2025-08-08T11:27Z) and/or CME: 2025-08-06T07:24Z (modeled to arrive at 2025-08-08T20:00Z).
