    Sun sights

    Dear Nav-listers,
    This is boring compared to recent lunar observations, but I am still trying to determine the position of my front garden using sun sights.  As advised by several of you, I moved past using meridian passage.  On Saturday I took three sights one approximately an hour before LAN, one at LAN and one approximately one hour after.  I then reduced the sights using H.O. 229 (which I discovered is a lot like doing your taxes) and plotted the results on a universal plotting sheet.  The plot showed that the altitude intercepts of the second and third sight intersected at a point very close to my GPS long/lat.  The first one, however, seemed out.  I ran my data through the on-line sight reduction calculator at <http://www.celnav.de/sightred.htm> and it confirmed the problem.  I cannot find my mistake.  Worksheet attached.  All assistance gratefully received.

    BTW, the garden is, relatively speaking, stationary.

    Best regards,
