The Altitude and Azimuth of the Sun or Moon During One Day application
is located at the following URL:

http://aa.usno.navy.mil/data/docs/AltAz.php

The site can also be reached as follows: Access the U.S. Naval
Observatory Home web site (at http://www.usno.navy.mil/ ); at the menu
of the left of this home page select the Astro Applications entry.
From the Astro Applications web page, select the Data Services entry.
From the Data Services web page, select Altitude and Azimuth of the
Sun or Moon During One Day.


I hope this may prove useful.

My article contains links to two spreadsheets, a basic one and an
enhanced one. The enhanced one contains macro functions that calculate
the Sun's position from the time data recorded by NFM (and your location
data). Of course, you need to make sure your computer clock is
syncronised before taking the measurements. The link to the enhanced
spreadsheet is in the Links section of
http://www.vk1od.net/nfm/application...ernFromSun.htm .

The spreadsheet uses a set of macro functions derived from the NOAA
calculator ant published by the Department of Ecology, Olympia WA.
