Re: Re: True North - Sorry - 1 hour error in originalcalc.



One more thing ... maybe you did mention it in your original
message.  Don't forget to include the equation of time in your
calculations.  The sun runs "fast" and "slow" during the calendar
year.  Right now, the sun is over 14 minutes "slow".  A sundial located at
your time zone meridian and your clock on the wall will differ by over 14
minutes today.  The sun moves 1 degree in 4 minutes.  Therefore, the sun
will be over 3 degrees away from true south (SE).
