    The Mean Motion of USA-179 is about to emulate world stock markets, but
    hopefully not fall too dramatically.
    
    It is getting close to the highest value since settling into the operational
    orbit, so a correction seems due. On past form, this will add about 0.2
    mnutes to the orbital period, currently measured at 717.65 minutes.
    
    The plot of measurements from radio observations, which includes some
    visually-derived values, is at:
