This map shows the path of the solar eclipse across Earth's surface. The northern and southern path limits are blue and the central line is red. The four-way toggle arrows (upper left corner) are for navigating around the map. The zoom bar (left edge) is used to change the magnification. The two buttons (top right) turn on either a map view, a terrain view, a satellite view or a hybrid map/satellite view.
See Eclipse Data, including the Besselian elements, for the -1140 October 20 solar eclipse.
Click anywhere on the map to calculate eclipse times there. For more information, see Instructions.
This Google Maps implementation (path computations, local circumstances and cursor position) is based on Xavier Jubier's Five Millennium Canon of Solar Eclipses Web Tool.
Special thanks to National Space Club summer intern Sumit Dutta for his assistance in preparing the solar eclipse mapper (July 2007).
These eclipse predictions were generated for the Moon's center of mass using the VSOP87/ELP2000-82 ephemerides and a value of ΔT = s. The resulting Besselian elements are the same as those used by the Five Millennium Canon of Solar Eclipses.
