This software from the Florida Solar Energy Center allows the user to select latitude and longitude coordinates for a site of interest (from a many-city library provided or by hand entry) and then determine the position(s) in the sky of the center of the sun for any day of the year and time of day, or for a sequence of days and times. The results are output into an ASCII file with columns labeled and conditions specified, easy to import into any word processing program, spreadsheet, or for direct printing.
