This provisional post-manoeuvre orbit for USA 224 is based on observations by
David Brierley and me:

USA 224
1 37348U 11002A   21165.00715133 0.00014912  00000-0  12302-3 0    05
2 37348  97.8892 276.6083 0530502 157.6427 204.8870 14.81006602    06

rms 0.01 deg   25 obs  arc Jun 13.00 - 14.01 UT


It appears that the manoeuvre was on June 10 near 14:14 UT. It looks to be a
normal orbit maintenance manoeuvre (raising apogee some 10 km) done while
perigee was at the equator.

Based on historic precedent, somewhere this summer I expect it to make a large
manoeuvre, switching orbital plane to the secondary east plane and lowering
apogee considerably.
