What counts as a space weather warnings

Space weather warnings describe solar flares, geomagnetic storms and radiation storms that can disturb satellites, GNSS positioning, high-frequency radio and power grids, and that produce aurora at unusually low latitudes. NOAA SWPC rates geomagnetic storms from G1 (minor) to G5 (extreme).

If a warning is active

• Expect degraded GPS accuracy during a strong geomagnetic storm.
• Protect critical infrastructure and expect HF radio outages on the sunlit side.
• Aurora can be visible far from the polar circle during G3 and above.
