    Re: Moon Venus Lunar - Interpretation of results

    Corrections to the math in my previous message:

    2300 UT Calculated LD:
    acos(sin(-2°34.7') · sin(-5°03.9') + cos(-2°34.7') · cos(-5°03.9') · cos(122°56.3' · 106°32.5')) = 16°32.8'

    ... should be:

    2300 UT Calculated LD:
    acos(sin(-2°34.7') · sin(-5°03.9') + cos(-2°34.7') · cos(-5°03.9') · cos(122°56.3' - 106°32.5')) = 16°32.8'

    *Note that the multiplication sign in the last term should have been a minus sign.*

    And the same for:

    2100 UT Calculated LD:
    acos(sin(-2°57.9') · sin(-5°06.5') + cos(-2°57.9') · cos(-5°06.5') · cos(92°56.8' · 77°22.0')) = 15°41.2'

    ... which should be:

    2100 UT Calculated LD:
    acos(sin(-2°57.9') · sin(-5°06.5') + cos(-2°57.9') · cos(-5°06.5') · cos(92°56.8' - 77°22.0')) = 15°41.2'

    There is, however, no error in the results - just a simple confusion of symbols. My apologies for any confusion this may have caused.

    -Sean C.
