The total solar eclipse of April 22nd ^jul. / May 3, 1715 ^greg. was visible in northernmost North America , Greenland , Europe , the Arctic and large parts of Asia , as well as the North Atlantic . The path of totality stretched from the Azores via England and Wales , across the West Frisian Islands , the extreme northwest of today's Schleswig-Holstein (then Danish), Denmark , Sweden , Finland and the north of the Russian Empire to Siberia . The longest duration of the solar eclipse of 4 minutes and 14 seconds was reached near the Swedish capital Stockholm . It is the first solar eclipse for which the forecast of its course was created as a map. Since the Gregorian calendar was not introduced in England until 1752, the solar eclipse of April 22nd is often used in contemporary English literature. The solar eclipse belongs to the Saros cycle 114.

Thanks to Edmond Halley's accurate forecast and good weather, an extensive observation campaign was carried out in England, which led to an improved forecast of the solar eclipse of May 22, 1724 . Furthermore, Halley discovered in his calculations deviations in the course of the totality zone of ancient solar eclipses, which can only be explained by the slowing down of the earth's rotation (see also Delta T ).
