    John,
    
    From my location at this time of the day on April 30, i.e. midafternoon, the
    moon is only going to be about 11 degrees from the sun. That makes it
    invisible in daylight. Almost a new moon.
    
    Therefore you should not see the station cross a lit moon anyway. Even so
    the sky in that area is going to be far brighter than the station.

    P.S. Filters don't darken the sky preferably (at least not much) when the
    sky you are looking at is that close to the sun. The sky is pretty white at
    that angle.
