Satellite & GPS Impact

Atmospheric drag

Increased geomagnetic and solar activity can heat and expand Earth's upper atmosphere, increasing aerodynamic drag on satellites in low Earth orbit — this can shorten predicted orbital lifetimes and complicate precise orbit prediction during active periods.

GPS / GNSS impact

Status: Low. Ionospheric disturbances driven by geomagnetic storms can introduce timing errors into GPS/GNSS signals. This reflects real, live geomagnetic conditions — not a confirmed outage report.

Satellite communications

Status: None. Possible impacts come from ionospheric disturbances, radiation, geomagnetic storms and solar radio activity — see the current radio blackout level below.

Radiation exposure

Current level: S0 — None

Orbital effects

During geomagnetically active periods, the upper atmosphere can expand measurably, increasing drag on low-Earth-orbit spacecraft and making precise orbit prediction more difficult for operators. Elevated solar activity (reflected in the real sunspot number below) is a useful long-term indicator of how active the Sun has been overall.

Conditions driving satellite impact

Why solar activity matters

The current real monthly sunspot number is 45.7. Higher solar activity generally means more extreme ultraviolet (EUV) output from the Sun, which heats and expands Earth's upper atmosphere — the same real mechanism behind the atmospheric-drag effects described above. This app does not currently have a live F10.7 radio flux feed; the real sunspot number is shown here as the closest available real indicator of overall solar activity level.
