    Cees Bassa, Russell Eberst, Kevin Fetter, Alberto Rango, Greg Roberts, Scott Tilley, Peter Wakelin, Mike Waterman and
    Brad Young, contributed observations used to update the following orbital elements.
    
    Alberto made another observation of USA 186 in its post-manoeuvre orbit on 2012 Jul 20 UTC. The object he reported as a
    possible USA 186 on Jul 21 is 79050A / 11389. Here is a revised rough TLE of USA 186:
    
    USA 186
    1 70000U          12202.81993812  .00028563  00000-0  24691-3 0    07
    2 70000  97.8982 264.8777 0540793  82.7763 283.4575 14.77988962    09
    
    On 2012 May 21 UTC, Cees observed an UNID that Mike McCants suspected was one of the three Helios satellites in "secret"
    orbits. Two of the three have since been identified; therefore, leaving Helios 2A (04049A / 28492) as the likely ID. If
    so, then it may be found within several minutes of the time predicted by this TLE:
