    Re: A Lunar Example: Sun and Moon vertically aligned

    Frank,

    In my previous solution to your 'vertical lunars' case, I forgot to include the GMT computation. The attached pdf has it.

    I was interested in your rules of thumb in finding such a case.  After working this example, I think those rules look something like this:

    - moon and sun simular Dec

    - Zn's of both bodies same or near so (obvious, if they are to be on the same vertical circle)

    - AP Lat of observer near Dec of the bodies

    - AP Lon of observer near the GHA of one of the two bodies not not the same

    Is this close?  I have to try using them to find another case.

    Ed
