The Besselian elements are valid over the period 16.00 ≤ t0 ≤ 22.00 TDT. Note that all times are expressed in Terrestrial Dynamical Time (TDT). Saros Series 149: Member 22 of 71 eclipses in series.

Eclipse Predictions

Predictions for the Total Solar Eclipse of 2043 Apr 09 were generated using the VSOP87/ELP2000-85 solar and lunar ephemerides and a value of ΔT = 86.4 seconds. The luanr coordinates have been calculated with respect to the Moon's Center of Mass. They DO NOT include a correction to the Center of Figure, or the effects of mountains and valleys along the edge of the Moon.
