Daily updates

Welcome to Spaceweather Horizon

Live Sun–Earth intelligence and a physics-based simulation suite, built and operated independently. This briefing is updated as conditions and the platform evolve — check back for notable events, forecast notes, and release announcements.

Real-time data

From global observatories and spacecraft at L1 — NOAA, NASA, GFZ, USGS.

Physics-based models

Published methods: DBM/RK4 propagation, Shue standoff, Burton Dst, ensemble forecasting.

Forecast accountability

Blind arrival predictions logged and verified against detected interplanetary shocks.

Independent

Built and operated by a single engineer. No trackers, no ads, no dark patterns.
