SolarStorm

Know when the Sun is acting up — live storms, flares, and aurora forecasts, with a two-week outlook and alerts when something big is coming.

SolarStorm turns live data into a clear, beautiful read on what the Sun is doing right now — and whether it matters to you.

Solar flares, geomagnetic storms, and radiation can disrupt GPS, radio, satellites, and power grids — and light up the sky with aurora. SolarStorm makes it simple to follow.
