    The 50 burn began at 0848xx (I don't know the exact seconds).
    The perigee was a few minutes earlier.
    [This info comes from a conversation with CONTOUR Operations Planning
    Engineer.]

    DG may have had a view, but they were not scheduled to be tracking CONTOUR.
    NASA's Deep Space Network has used five antennas to search for it (two
    antennas at Goldstone in California, two in Australia, and one in Spain)
    with no success.
