A total solar eclipse occurred on 3 May 1715. It was known as Halley's Eclipse, after Edmond Halley (1656–1742) who predicted this eclipse to within 4 minutes accuracy. . Halley observed the eclipse from London where the city of London enjoyed 3 minutes 33 seconds of tota
Halley's albedo, for instance, is about 4%, meaning that it reflects only 4% of the sunlight hitting it – about what one would expect for coal. [73] Thus, despite astronomers predicting that Halley would have an albedo of about 0.17 (roughly equivalent to bare soil), Halley's Comet is in fact pitch black. [74]

The details of Edmund Halley's visit to Newton in 1684 are known to us only from reminiscences of thirty to forty years later. According to one of these reminiscences, Halley asked Newton, "what he thought the Curve would be that would be described by the Planets supposing the force of attraction towards the Sun to be reciprocal to the square ...
In his report, Halley suggested places that a full transit should be viewed due to a "cone of visibility". Places he recommended for observing the phenomenon included Hudson Bay, Norway and the Molucca Islands. [6] The next transits would occur in 1761 and 1769. Halley died in 1742, almost twenty years before the transit. [7]
