Besselian Elements for the Annular Solar Eclipse of 2014 Apr 29

The Besselian elements are valid over the period 3.00 ≤ t0 ≤ 9.00 TDT. Note that all times are expressed in Terrestrial Dynamical Time (TDT). Saros Series 148: Member 21 of 75 eclipses in series.

Eclipse Predictions

Predictions for the Annular Solar Eclipse of 2014 Apr 29 were generated using the JPL DE405 solar and lunar ephemerides and a value of ΔT = 67.3 seconds.
