    USA-179 is heading for one of its major orbit adjustments in the next week
    or so. See:
    http://www.zarya.info/Tracking/USA179/USA1792007H2.php
    
    Maybe it will coincide with USA-198 settling down into its operational
    location? The last manoeuvre of USA-179 did not fit the normal pattern. A
    small retrograde adjustment three days before USA-198's launch was followed
    by an unusually long non-manoeuvring period.
    
    The value of ndot2 still comes through quite nicely from watching the rate
    of change indicated by the VHF switching data:
    http://www.zarya.info/Tracking/USA179/USA179deltaN.php
    
    Current values:
    n - 2.0068
    ndot2 - .000013
