Annular solar eclipse of 28 February 2063
A annular solar eclipse crosses the Earth on 28 February 2063. Along a track 265 km wide the Moon sits centred on the Sun but is too small to cover it, leaving a ring of sunlight for up to 7 min 41 s. The central line runs across Fiji, Indonesia and the Philippines. From Padang the central phase runs 6 min 12 s, with the Sun 35° 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. 537 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.
