    After a hot summerday, the night was warm and clear.
    After 22 UT the moon interferred.
    I got up early and saw another pass of 04-21 B.
    But the moonlight disturbed even more and I stopped observing.
    
    Saw this mornings launch of Messenger to Mercury and I'm now
    watching the spacewalk from the ISS on Nasa TV.

    A higher pass (20-30 degrees elevation) from the north to NW.
    The next pass would be almost overhead, but after 03 UT and the
    sky would be too bright.
