Well, I observed 16d00m, adding the semi diameter of the moon gives
16d15m.  My program predicted 16d20M25S or a near limb of 16d5M for my
location.

George Huxtable predicted the 16d05.1M for the near limb.

So it looks like George, you, and my program agree on the
prediction,  guess my measurement was 5M low.  I actually made a series of
measurements
which were consistently low, I even used two different instruments. I can't
believe the Venus disk is a problem since it's diameter is 15 seconds.

Thanks to both you and George for the help! :-)
