A totalsolar eclipse occurred on 3 May 1715. It was known asHalley's Eclipse, afterEdmond Halley (1656–1742) who predicted this eclipse to within 4 minutes accuracy. Halley observed the eclipse fromLondon where the city of London enjoyed 3 minutes 33 seconds of totality. He also drew a predictive map showing the path of totality across theKingdom of Great Britain. The original map was about 20 miles off the observed eclipse path, mainly due to his use of inaccurate lunarephemeris. After the eclipse, he corrected the eclipse path, and added the path and description of the1724 total solar eclipse.[1]
Drawing upon lunar tables made by the first Astronomer RoyalJohn Flamsteed,William Whiston produced a more technical predictive eclipse map around the same time as Halley. Both Halley's and Whiston's maps were published byJohn Senex in March 1715.[2][3]
Totality was observed in the Kingdom of Great Britain fromCornwall in the south-west toLincolnshire andNorfolk in the east. It was also observed inIreland, where large crowds turned out inDublin to watch it: the weather in Dublin was exceptionally cold and wet, and the eminent judgeJoseph Deane caught a fatal chill as a result,[4] although Elrington Ball more prosaically states that his death was probably due togout.[5]
Note: Great Britain did not adopt theGregorian calendar until 1752, so thedate was at the time considered 22 April 1715.
