Solar Weather - Space Forecast

Solar flare animations, Kp index, aurora forecasts — all in real time from NOAA and NASA data, in a beautiful and intuitive interface!

Track real-time solar activity and get accurate space weather forecasts with Solar Weather. From Sun animations to aurora predictions — professional observatory data, designed to be easy to read and use.

What's happening on the Sun right now?

• Live UV solar animations across 7 wavelengths — from surface details to violent flare regions
• Coronagraph views: GOES-19 (CCOR-1), LASCO C2 and C3 — watch coronal mass ejections unfold from different distances
• Swipe through 24-hour solar animations almost minute by minute — full manual control over Sun, Aurora, and Coronagraph views
• Export any animation as a shareable video

Will there be an aurora tonight?

• Aurora map showing real-time intensity and coverage for both hemispheres
• 1-hour aurora visibility forecast based on current solar activity
• Kp index: 3-day forecast, 1-week history, and a combined real-time graph
• Solar Wind Speed, Magnetic Field Bt & Bz — the key indicators that trigger geomagnetic storms
• When Bz goes negative, aurora chances spike — and the app helps you spot it

Never miss a space weather event:

• Push notifications for Geomagnetic storms, Solar Radiation storms, and Radio Blackouts
• Set your own alert thresholds — only get notified for the storm levels that matter to you
• Geomagnetic and Radiation storm forecasts up to 3 days ahead
• Daily solar activity index (10.7 cm Radio Flux)
• Home Screen and Lock Screen widgets with real-time data

Explore the Sun in detail:

• Hot Flares: the most intense solar eruptions captured in extreme ultraviolet
• Solar Corona: the Sun's outer atmosphere — millions of degrees hot, rarely seen up close
• Active Regions: areas of powerful magnetic activity where flares and CMEs originate
• Transition Zone: the dynamic boundary between the chromosphere and corona
• Chromosphere: the Sun's colorful middle layer, visible during eclipses
• Surface: sunspots, granulation, and intricate magnetic patterns

Built for space enthusiasts, amateur astronomers, and anyone curious about the Sun. Solar Weather pulls data directly from NOAA and NASA to give you an accurate, up-to-date picture of solar activity and its impact on Earth.
