The Eclipse Explorer presented here features drop-down menus for city coordinates and buttons to select any century from -1499 to 3000 (1500 BCE to 3000 CE). It can be used to explore the frequencey and circumstances of all solar eclipses visible from any location on Earth. The Eclipse Explorer was developed by Chris O'Byrne and Fred Espenak.
The Besselian elements and values of ΔT used in Solar Eclipse Explorer are the same as those used by Five Millennium Canon of Solar Eclipses: -1999 to +3000. For the purposes of calculating eclipse circumstances from a given place, the growing uncertainty in the value of ΔT and the corresponding longitude become unacceptably large outside time period of -1499 to 3000 (1500 BCE to 3000 CE).
