Ephemerides of Neptune:

The Ephemeris of Neptune have been calculated for my observation point, the times are expressed in Local Civil Time, and the apparent geocentric equatorial coordinates were calculated for the 0.0 hours of the day indicated and refer to the average equinox of the date.
In the calculation of equatorial coordinates the (T.T) Terrestrial Time count was taken into consideration by applying a correction of 67 seconds (U.T), including the Light-Time correction.
For the calculation I used the algorithm described by authors JEAN MEEUS and P.D. SMITH.
At the bottom of the page you can find some useful instructions on how to insert this chart inside your site with the possibility of configuring it with the coordinates of your location.

Location: IRGOLI (Italy) LAT. 40° 24' 42" North - LONG. 9° 38' 8"East - ALT. 30m.a.s.l.
