    Re: moon visible by day...
    From: Jan Bruggeman

    hello all,
    The day (24 h) is (used to be) divided into 4 "quarters", 2 for day (first
    and last) and 2 for the night (also called first and last).
    This means that the start of the day is 0600 and the start of the night is
    1800.  Wright ?
    if declination is 0, yes. otherwise, we do not see 180 of the object's
    rotation. It can be more, when the declination of the object is towards us,
    or less, if otherwise.
    as example, consider the sun in summer: declination is to our side: we see
    more than 180 degrees of the path of the sun, which makes for a longer day.
    Winter is just the inverse: declination is away from us. Expressed this way,
    it holds true wherever you are.
    This also accounts for the small differences between my theoretical and your
    practical approach.
