Disk No: 2862 Disk Title: AstroMeeus PC-SIG Version: S1 Program Title: AstroMeeus Author Version: 0.9 Author Registration: $25.00 Special Requirements: Windows 3.0. This is a Windows based astronomy ephemeris program. In addition to producing the traditional sun, moon and planets phenomena charts, ASTROMEEUS will also produce a monthly calendar of astronomical events with sunrise/set, moonrise/set for each day, the phases of the moon, and the time of any equinoxes, solstices or eclipses. The calendar uses Windows vector fonts and can produce some very attractive output, suitable for hanging on the wall. ASTROMEEUS is based on the book Astronomical Formulae for Calculators by the renown Belgian astronomer Jean Meeus. The calculations in his book yield very good results and are applicable for a wide range of dates, not just for the 20th century. The easy-to-use Windows interface provides hypertext help, list boxes with over 150 North American cities to set the longitude/latitude configuration, scrolling output, colorful icons and dialog boxes for converting Julian dates to calendar dates and many other functions. Calculations and charts displayed on the scrolling window may be saved to an ASCII file. The following calculations are available (Julian dates must be after 4713 B.C.): ~ Position of the Sun (apparent or geometric) ~ Times of sunrise, transit, sunset and twilight (Civil, Nautical or Astronomical) ~ Equation of time ~ Equinox and Solstice times ~ Position of the Moon ~ Times of moonrise, transit, moonset and phase ~ Graphic display and readout of the position angle of the moon's bright limb ~ Times of full moon, first quarter, full moon and last quarter ~ Eclipse times ~ Positions of the planets (heliocentric and geocentric) ~ Rise, transit and set times for the planets ~ The phase or illuminated fraction for each planet PC-SIG 1030D East Duane Avenue Sunnyvale Ca. 94086 (408) 730-9291 (c) Copyright 1989 PC-SIG, Inc.
