Satellite and radar imagery are powerful tools to forecast cloud cover and decide if the night is good for astrophotography.
Satellite Imagery
Infrared and visible-light satellite maps show cloud formations and movement across large areas. Look for:
- Cloud thickness and type (thin cirrus vs. thick stratus)
- Movement trends indicating clearing or worsening conditions
Weather Radar
Radar detects precipitation and dense cloud layers. Use radar to:
- Spot incoming rain clouds that could damage gear
- See dense cloud patches that might block stars
Combine these tools with local weather forecasts and real-time sky observations for the best results. Many apps and websites provide easy access to these images, helping you plan your shoot with confidence.
