    Although many debris pieces have been cataloged, only the first
    set of about 30 have RCS values in the Satellite Situation
    Report for February 5.  The largest RCS is 0.036 square meters
    and there are a few near 0.027, but most are smaller.
    So I would assume that these pieces would normally be down
    at magnitude 10 or 11 or fainter.  Perhaps some of the newer
    500 pieces will be larger and perhaps one of the next SSRs
    will have larger RCS values.
    On the other hand, it might be reasonable to assume that many
    of these pieces will be irregularly shaped and spinning rapidly.
    If so, they might give visual flashes much brighter than their
    RCS might indicate.  But human eyes are better at spotting such
    flashes than a video system (in my opinion).
