Bearing to sunrise & sunset. Message #1 Posted by r. d. bärtschiger. on 26 June 2002, 12:14 a.m.
Does anyone know of a program for the hp-48gx or hp-49, or alternately just an equation, which will allow the followinmg to be calculated?
Given a location on earth in degrees lat. & long. & the date, calculate the true bearing to where the sun will rise & set on that date. If the times of sunrise & sunset are also calculated, that would be even better.
I have checked the selection of programs available on hpcalc.org but did not find anything similar.
Thank you for any information you can offer.
