    Peter Wakelin has recovered USA 236 (12033A / 38466), which appears to have slowed or stopped its eastward drift.
    
    The following is a guess, assuming it is now synchronous near 13 W:
    
    1 70000U          13076.30219851  .00000000  00000-0  00000-0 0    06
    2 70000   4.3893 271.0836 0004340  79.9368 279.8235  1.00273800    03
    
    I have found USA 236 puzzling. Since USA 227 (11011A / 26635) replaced SDS 3-1 (00080A / 26635) at 10 W, I expected USA
    236 to replace SDS 3-2 (01046A / 26948) near 144 W. USA 227 was checked out near 30 W for about 3 months before taking
    over at 10 W, so I expected USA 236 to be checked out close to 144 W before taking over that location. Instead, it went
    straight to 30 W, where it was checked out for about 7 months, and now show signs of becoming operational near 13 W,
    just 3 deg W of USA 227. Meanwhile, SDS 3-2 has moved to 141 W. The next SDS launch may be NROL-33, in FY2014, but it be
    a NOSS.
