    Peter Wakelin has observed his UNID again, confirming that its mean motion is
    near 2.006 rev/d:

    Here are updated elements, using the designation assigned by Mike McCants:
    
    08628A           0.0  0.0  0.0  4.5 v
    1 90081U 08628A   08128.60175929  .00000000  00000-0  00000-0 0    03
    2 90081  62.8204 215.2087 6814408 276.8656  16.0137  2.00587822    00
    Arc 2008 May 07.12 - 08.14, WRMS residuals = 0.006 deg
    
    Peter raised the possibility that this could be one of the three Trumpets,
    launched during 1994-97. It may well be, and the other two may be among the
    other UNIDs currently tracked in Molniya orbits. I plan to devote some time to
    studying their orbits and observed characteristics, in an effort to identify the
    Trumpets, and determine their correct designations. This effort will be aided by
    our having tracked and reliably identified two of the Trumpets for several
    years, most recently in 2003.
