About this app
Witnessing a total solar eclipse is one of nature's most awe-inspiring spectacles. Don't leave your location to chance.
Eclipse Tracker is the ultimate tool to plan your observation. Designed with scientific rigor, it combines advanced mapping, real-time weather, and space simulations to ensure you are in the exact place at the precise moment.
šŗļø The best spot, instantly
ā¢ Official shadow path and centerline (NASA / IGN Spain)
ā¢ Score heatmap blending duration, altitude, terrain and clouds
ā¢ Totality duration isochrones
ā¢ Historical climatology (NASA POWER) and live forecast (Open-Meteo)
ā¢ Bortle/SQM light-pollution overlay powered by VIIRS
šļø Terrain matters
ā¢ Real DEM elevation (Terrarium) on every point you tap
ā¢ 360Ā° horizon sampled against worldwide topography
ā¢ Visual warning when a mountain blocks the solar disk
š A real 3D simulator
ā¢ Real ephemeris based on JPL DE421 (astronomy-engine)
ā¢ Sun with corona, chromosphere, diamond ring and prominences
ā¢ 3D Moon with Lambert shading and proper libration
ā¢ Deep sky: 100,000+ stars (HYG), 21 constellations, Messier catalog
ā¢ Shadow bands and Baily's beads rendered in GLSL
ā¢ AR mode driven by your device's orientation
š¬ SCIENTIFIC PRECISION
Every value comes from authoritative sources: NASA GSFC, IGN, IAU, JPL Horizons, Hipparcos and the HYG Database. Every number on screen tells you exactly where it came from.
