    The current orbit of usa 129 is very nearly 15 revs/day,
    and I have had 2 passes each evening at close to the
    same alt-az on successive days. I dont recall this happening
    in previous years since launch. Am i getting forgetful in my old age?
    The configuration is annoying because neither pass is high.
    Comments anyone?
    Incidentally tracking of USA 129 by me will cease by february 20 this
    observing season as shadow entry will be at too a low an elevation.
