    10015A / 36514 was a no-show for Brad Young, on 2010 Oct 07, near 11:50 UTC, on what he described
    as, "a fair pass":

    Culmination was 23 deg; predicted magnitude was 4; phase angle was reasonable.
    
    It was a no-show for me this morning, Oct 09, at 10:29:11 UTC, on a pass similar to Brad's.
    
    These are my latest elements of the last known orbit.

    The last reported observation was by Greg Roberts, on Oct 05, near 18:48 UTC, so the time of the
    apparent manoeuvre can be narrowed to about a 1.7 day period, which should help in planning a
    search. Unfortunately, I have run out of analysis time for now, and an unlikely to be available
    until after 23 h UTC.
