- MOONCLOCK produces a continually updating, real-time graphical
- representation on the visual aspect of the moon. The lunar aspect
- may be computed geocentrically, or topocentrically, for the
- current epoch, or for any time and date.
-
- MOONCLOCK will run on any Macintosh computer, or other platform
- running the Macintosh Operating System, or Macintosh Application
- Environment. A native PowerPC version of MOONCLOCK, called
- MOONCLOCK PPC is available. To start MOONCLOCK just double click
- on the MOONCLOCK icon.
-
- The dynamic MOONCLOCK graphic depicts how the moon would appear
- to the observer. The light and dark shaded portions of the lunar
- graphic represent the regions of lunar day and night. The direction
- from the Moon's center to celestial north is also indicated. To the
- tight of the lunar graphic the following information is presented:
-
- * The lunar elongation angle (measured eastward from the sun)
- * The position angle of the bright limb (measured eastward from
- celestial North to the mid-point of the bright limb)
- * The percentage of the lunar surface illuminated by sunlight
- * The current (or selected) Universal Time and Date
- * The geographic longitude at which the sidereal time is 0 hours
- * The observer's sidereal time
-
- An instantaneous lunar ephemeris is presented in the bottom of the
- MOONCLOCK window. The header for the ephemeris indicates
- whether positional computations were performed geocentrically or
- topocentrically, and the epoch of the ephemeris as both Julian and
- Gregorian dates.
-
- The lunar Right Ascension, Declination, Heliocentric Latitude,
- Heliocentric Longitude, apparent angular Equatorial Radius, and
- Distance from the Earth is displayed. The equatorial coordinates
- of the moon are precessed to the equator and equinox of 2000.0. A.D.
- The lunar distance is expressed in Earth radii. The lunar angular
- radius is expressed in seconds of arc.
-
- Please see the HELP item in the MOONCLOCK menu for more
- information.

- MOONCLOCK provides a high precision lunar ephemeris, with an
- accumulated error of less than 15-arc seconds per century from
- 1990.0. MOONCLOCK was developed using kernel software supplied
- with HIPPARCHUS, a fully integrated Macintosh application for
- positional and observational astronomy, from sofTouch
- APpLications.
-
- This software was developed using APL.68000, a proprietary product
