Total solar eclipse of 15 December 2039
A total solar eclipse crosses the Earth on 15 December 2039. Along a track 120 km wide the Moon blocks the Sun completely, and totality lasts up to 1 min 51 s. The central line runs across Antarctica.

See it in 3D
The simulator places the Sun, Earth and Moon at their true relative positions for this date and draws the shadow cones at real scale. You can scrub through the eclipse, drop an observer anywhere, and watch the umbra sweep the surface.

Local circumstances
This eclipse misses every city in the database — the track falls over ocean or polar regions. Use the 3D simulator to place an observer anywhere on Earth and read off the contact times for that point.
How these figures were produced
Positions come from astronomy-engine, a VSOP87/ELP implementation. From the geocentric Sun and Moon vectors the site computes Besselian elements — x, y, d, μ, l1, l2, tan f1 and tan f2 — and solves the observer's position on the fundamental plane against the WGS84 ellipsoid. Central durations agree with NASA's Five Millennium Canon to within about half a second. Full method and validation.
