An excellent source for weather prospects for upcoming eclipses is meteorologist Jay Anderson's Eclipse Weather Page. ↩
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.
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:
