Like a planetarium, this program lets you view the sky and the heavenly bodies at any time, date, latitude or longitude. Over one hundred sixty stars, nine planets, the sun and moon are shown in a circular plot of the sky. Although the program is not made for astronomers, astronomical terms and concepts are used. Chief among these is the concept of sky coordinates. Numeric data about the position of the planets, sun and moon is available in any of three coordinate systems.
Optional programs are available to plot the sky in alternate coordinates.
Transfer the file 'Sky' to your HP48, into any directory you like. When the transfer is complete, you will have a new directory called 'Sky'. Less memory will result in an error while trying to run the display. These are 'Sky's user words. Subsequent pages are filled with support words that are used by the program.
