    Not sure whether this is earlier or later than the source used by Bob, but the most recent ISS status report gives a separation time of approximately 1020 UTC.  (Spaceflight Now says 1000 UTC but I guess that may be based on older information.)
    I guess there may be some change to the trajectory before the deorbit burn but in any case we could not have any illuminated passes here during the timeframe between separation and splashdown.
    However there is a significant New Zealand connection in that Auckland University of Technology is tasked with monitoring the de-orbit and advising Space-X of the location of splashdown.
    So John if you want to know when and where the burn and estimated splashdown will occur you could perhaps contact AUT directly.
    (NASA-TV commences its coverage of the burn and splashdown from 1415  UTC onwards and no doubt that coverage would commence a few minutes or more before the burn is due to happen.)

    NASA has published some actual times, undocking from Harmony using the 
    RMS - 10:10 UTC, splashdown - 15:44 UTC.
