* Ephemeris Longitude is the terrestrial dynamical longitude assuming a uniformly rotating Earth. ** True Longitude is calculated by correcting the Ephemeris Longitude for the non-uniform rotation of Earth. (T.L. = E.L. - 1.002738*T/240, where T(in seconds) = TDT - UT)
Note: Longitude is measured positive to the East. Since T is not known in advance, the value used in the predictions is an extrapolation based on pre-2003 measurements. Nevertheless, the actual value is expected to fall within ±0.3 seconds of the estimated T used here.
