    There's an article in
    titled "LMT Data Reduction Continues" that contains some interesting data on
    numbers of "uncorrelated targets", aka UCTs, (unknowns) detected by a NASA
    optical debris survey. The basic message is that they saw hundreds of UCTs
    if catalogued by USSPACECOM, presumably would be assigned 8xxxx catalog
    numbers and not be disseminated by OIG.
    Most of the UCTs NASA detected were quite faint, but several had an
    visual magnitude as bright as 5.  It appears that NASA defines a.v.m. for
    using a nominal range of 1,000 km -- I'm not sure about the phase angle.  In
    event, some may have been bright enough to be seen by SeeSat observers.
