    Here are last night's results  using Frank's calculator. I allowed the calculator to determine the altitudes of Venus and the Moon.

    Sight 1

    Error in Lunar  -1.5'

    Error in long  45.8' (approx 3 min time?)

    Sight 2

    Error in lunar -3.9'

    Error in long 1° 57.6' (30 min time?)

    Sight 3

    Error in lunar  0.3'

    Error in long 07.5'  (approx 30 seconds time?)

    I reworked sight 3, using my observed altitudes

    Error in lunar -0.8'

    Error in long  22.5'  (approx 1.5 min time?)

    Referring to the altitude observations my old school teacher would say Must try harder.
