    USA 202's manoeuvre appears to have occurred at an apogee, probably that of Jun
    27 near 19:12 UTC, in which case the following should be fairly accurate:

    Alberto observed 09023B last night. I do not have Ed Cannon's observation of
    June 28 UTC, but I included a synthetic observation based on Mike McCants' epoch
    09179.08500624 elements, which he derived with the help of Ed's observation.
    Allow for at least 30 s prediction time uncertainty tonight.
    
    My 09023B evening visibility window is now wide open, but I expect cloud again
    tonight.
