    I observed the NOSS 3-4 pair on a 13 deg pass; they were 140 s late, and at
    least 0.1 deg above-track, relative the epoch 07303.18 elements.

    I was barely able to resolve STS 120 and ISS as separate objects, about 22 min
    after they undocked, using 25x100 binoculars. This was near the culmination of
    my pass, at 10:54:28 UTC, 21 deg above the south-eastern horizon, range 841 km,
    at which time Spaceflight Now reported the shuttle was 300 ft in front of ISS.
    
    At the range of 841 km, their angular separation was 22 arc sec, which would
    have been easy to split, except for the glare from the brilliant station. The
    station had an orange cast, which became more pronounced as it receded toward
    the eastern horizon.
    
    Comet 17P/Holmes remains an impressive object, readily visible to the unaided
    eye as a large, round, nebulous object. Its central core has expanded
    considerably, and no longer appears stellar in 25x100 binoculars. The coma
    appeared to be in excessive of 0.2 deg across.
