    As Bjorn Gimle has pointed out, USA 161 (01044A / 26934) is likely to have
    manoeuvred on or about 2008 Mar 19 UTC, the same day that USA 186 (05042A /
    28888) manoeuvred:

    I offer the following search elements, based on manoeuvres on Mar 19 and 20 UTC,
    respectively.
    
    USA 161         15.0  4.0  0.0  5.2 v
    1 79001U          08079.70295140  .00001495  00000-0  30000-4 0    08
    2 79001  97.8833 192.4394 0471000  25.5066   1.7800 14.75900000    07
    
    1 79002U          08080.58046297  .00001495  00000-0  30000-4 0    04
    2 79002  97.8833 193.3062 0471000  22.6422   1.7800 14.75900000    04
    
    The above epochs correspond to perigee passages within the typical daily time
    span of such manoeuvres.
    
    I suggest looking at least 5 min earlier than predicted by 79002 and 5 min later
    than predicted by 79001, with allowance for Earth's rotation in the interim.
