Path of the Annular Solar Eclipse of 1831 Feb 12

Fred Espenak

The following table delineates the path of the Moon's antumbral shadow during the Annular Solar Eclipse of 1831 Feb 12 . 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 .

Predictions for the Annular Solar Eclipse of 1831 Feb 12 were generated using the VSOP87/ELP2000-82 solar and lunar ephemerides and a value of ΔT = 7.0 seconds. The accuracy of the northern and southern edges of the eclipse path are limited to approximately 1-2 kilometers due to the lunar limb profile.

All eclipse calculations are by Fred Espenak, and he assumes full responsibility for their accuracy. Permission is freely granted to reproduce this data when accompanied by an acknowledgment:
