The Ephemeris of Mars 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.

Copy and paste this list onto your Web page, in the seciton<head></head> right after the tag<title> Listing (1) Copy and paste the codes for the style sheet (CSS), in the section Style Block, or create an external file. This listing is not fundamental but it serves to draw the chart of the ephemeris, just like the one on this page. Listing (2) Copy and paste the last listing in the section <body></body> Replace the values LAT, LON, ALT with those of your location. Listing (3)
Warning! The calculation will not be made for negative values of the iterations.
More information on how to insert a table of ephemerides, were included in the page Ephemeris Sun.
