    Previous night and to night I took a couple of hours to find 31702, 2007-027B.
    The first night I was unsuccesful because the clouded part of the sky was almost
    always in the direction where I wanted to search. The second night I was
    unsuccesful because I probably missed this Centaur rocket for a yet unknown
    reason. May be I looked at the right place at the wrong time or when I looked
    this probably variable object was at its faintest. My search was between about
    00h 30m and 02h 15m and was interrupted for several times a couple of minutes to
    check the time and the possible track of this object.
    
    In between I saw the 1996-029-trio of which the trailer is rather spectacular
    with two mag. -1 flashes. I also found the A- and C-components of the
    2007-027-launch and was able to determine some positions with the aid of Guide
    8.
