    Re: Venus mer-pass for Lat, Sun time sight for Lon.

    I plot your Ho values, then fit a quadratic through them.  Solving for the Ho's at 1215, I then use the two LOPs.  I get 60d 11.2' N, 29d 56.3 E.  The Venus line looks good to 0.5nm, but the sun line seems about 5 miles off.  Certainly could be my error.  I found Andres Ruiz' program very helpful.

    At 1215, Sun 32d 20.49', Venus 54d 31.00'
