the height of the sun at local noon is 90° - your latitude + sun's

I wrote an application in PostScript a couple of years ago that printed out the

Hello Brook,
to calculate the exact values of the position of the Sun in sky, you may use
the program SUN_EPH that has been attached to Compendium June 2003, Email

outage. I have since been making dots on the ceiling and noting the time and
date. Today, 3 Feb. 2005 the Sun at 12:00:00 noon was at the same place it was
