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

    hello all,
    
    Sorry for eventual mistakes, I'm translating literally from dutch.
    
    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).
    
    a celestial object is "visible" during more or less (see declination) 180
    degrees of it's daily 360 degrees trip, thus is visible during 2 quarters.
    
    a first quarter moon is visible during the "last quarter" of the day and the
    "first quarter" of the night, hence it's name.
    
    a full moon is visible during both first and last quarter of the night.
    
    a last quarter moon is visible during the last quarter of the night, and the
    first quarter of the day, hence it's name.
    
    a new moon is visible during both first and last quarter of the ... day!
    
    hope this helps,
    
    mvg,

    Subject: moon visible by day...
    
    
    I'm often intrigued by comments from people about the moon being visible
    over here during the day. (I'm in Cape Town at 34 deg south) Is this unusual
    in any other parts of the world since I had always assumed that it would be
    equally visible by day else here? Or is this just ignorance because the moon
    is assumed to be nocturnal?
    
    regards
    Russell
