This program computes the basic geocentric lunar ephemeris statistics for
any date, time and local time zone at any given moment within the 600-year
span from 1600 to 2200.

It computes the basic geocentric lunar ephemeris statistics which are
given below:

Coordinates, distance and phase image of the moon at any given moment:
Right Ascension
Declination
Distance in kilometers and miles
Phase Angle
Phase Description
Phase Image


Dates, times, coordinates and distances of the lunar quarter phases:
New Moon
First Quarter
Full Moon
Last Quarter moon

Dates, times and coordinates of distance extremes:
lunar apogee  - Moon at maximum orbital distance
lunar perigee - Moon at minimum orbital distance

TECHNICAL DATA

Ephemeris Model : NASA/JPL Development Ephemeris (DE405).
Applied Delta T : NASA polynomial expressions, resolved to nearest second.
Nutation Series : IAU 1980 Nutation Series.
Time Scale Used : Astronomical TT scale used for internal computations.

The DE405 ephemeris spans the 600-year range from 1600 Jan 01 to 2200 Dec 31
on the modern Gregorian calendar.

The computations are referred to the true ecliptic and equinox of the date.
