Circumstances at
Greatest Eclipse:   Sun´s Altitude =  67.3°         Path Width = 183.5 km
                     Sun´s Azimuth = 148.6°   Central Duration =  04m06.7s

1 Ephemeris Longitude is the terrestrial dynamical longitude assuming a
                     uniformly rotating Earth.
2 True Longitude is calculated by correcting the Ephemeris Longitude for
                the non-uniform rotation of Earth.
   (T.L. = E.L. + 1.002738*ΔT/240, where ΔT(in seconds) = TDT - UT)

Note: Longitude is measured positive to the East.

Since ΔT is not known in advance, the value used in the predictions is an 
extrapolation based on pre-2006 measurements.  Nevertheless, the actual 
value is expected to fall within ±0.5seconds of the estimated ΔT used here.
