Path of the Total Solar Eclipse of 1764 Sep 25
Fred Espenak
Introduction
The following table delineates the path of the Moon's umbral shadow during the Total Solar Eclipse of 1764 Sep 25 . The geographic coordinates (WGS 84) of the northern and southern limits and the central line are listed at 120-second intervals. This provides adequate detail for making plots of the path on larger scale maps. Local circumstances on the central line include the ratio of the apparent diameters of the Moon to the Sun, the Sun's altitude and azimuth (degrees), the path width (kilometers) and the duration on the central line (minutes and seconds). See the Explanation of the Central Eclipse Path Table for a description of each column in the table.
The geographic visibility of the eclipse is shown on a global map on the Prime Page for the Eclipse which also includes complete details on the eclipse. The path of the eclipse is displayed in greater detail on an interactive Google Map .

Eclipse Predictions
Predictions for the Total Solar Eclipse of 1764 Sep 25 were generated using the JPL DE406 solar and lunar ephemerides. The lunar coordinates were calculated with respect to the Moon's Center of Mass. Although the predictions are first calculated in Terrestrial Dynamical Time (TD), they are then converted to Universal Time (UT1) as presented here. The parameter ΔT is used to convert between the two times (i.e., UT1 = TD - ΔT). ΔT has a value of 15.0 seconds for this eclipse. The uncertainty in ΔT is 2.4 seconds corresponding to a standard error in longitude of the eclipse path of ± 0.01°.
