Path of the Total Solar Eclipse of 2017 Aug 21

Fred Espenak

The following table delineates the path of the Moon's umbral shadow during the Total Solar Eclipse of 2017 Aug 21 . 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).

The global visibility of the eclipse is shown on an Orthographic Map . The features of this map are described in the Key to Solar Eclipse Path Tables. The path of the eclipse is displayed in greater detail on a Google Map .

Eclipse Predictions

Predictions for the Total Solar Eclipse of 2017 Aug 21 were generated using the JPL DE405 solar and lunar ephemerides and a value of ΔT = 68.4 seconds.

The eclipse predictions presented here DO NOT include the effects of mountains and valleys along the edge of the Moon. Such corrections for the lunar limb profile may shift the limits of the eclipse path north or south by ~1-3 kilometers, and change the eclipse duration by ~1-3 seconds. More detailed predictions including the effects of the lunar limb profile are normally posted 12-18 months before each eclipse,
