Umbra.

Annular solar eclipse of 2 July 2038

A annular solar eclipse crosses the Earth on 2 July 2038. Along a track 31 km wide the Moon sits centred on the Sun but is too small to cover it, leaving a ring of sunlight for up to 1 min 00 s. The central line runs across Colombia, Venezuela, Morocco, Mauritania, Mali, Algeria and Niger, and more. From Pereira the central phase runs 1 min 31 s, with the Sun 10° above the horizon.

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

All times are UTC. Contact times are computed for each city from the Besselian elements against the WGS84 ellipsoid, at sea level and without refraction.

C1 and C4 are first and last contact, when the Moon's disc touches the Sun's. C2 and C3 bracket the central phase. 848 of the 2,250 cities in the database see at least a 3% partial eclipse.

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.
