Annular solar eclipse of 23 July 2093
A annular solar eclipse crosses the Earth on 23 July 2093. Along a track 198 km wide the Moon sits centred on the Sun but is too small to cover it, leaving a ring of sunlight for up to 5 min 11 s. The central line runs across the United States, Canada, the United Kingdom, Germany, Poland, Slovakia and Ukraine, and more. From Wrocław the central phase runs 4 min 41 s, with the Sun 51° above the horizon.

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. 998 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.
