Description

The Astronomical Almanac application calculates the exact position of objects in the solar system, their sunrise and sunset for a given time and place. The time of the onset of the lunar phases and lunar days is also calculated.
To improve the accuracy of determining the location of the observer, geographical maps are used.
Calculations are made in the date range from 3000 BC. until 3000 A.D.
The program uses the Steve Moshier algorithms.
Designed for astronomical observations.
The following parameters are calculated for celestial objects:
 - UT, TDT, Julian Day
 - Sideral time, Delta T
 Ecliptic:
 - Longitude
 - Latitude
 - Radius vector
 - Geocentric distance
 - Elongation from the Sun
 Visible geocentric:
 - Longitude
 - Zodiac
 - Right ascension
 - declination
 - constellation
 Astrometric:
 - J2000, Right Climb
 - J2000 Declination
 - B1950, right ascension
 - B1950 Declination
 Topocentric:
 - height
 - Azimuth
 - Right ascension
 - declination
 Properties:
 - Equatorial diameter
 - Visible value
 - phase
 Miscellanea:
 - time of light
 - nutation
 - Aberration
 - Parallax
 - sunrise
 - Meridian
 - sunset
 - Visible time
