    According to NASA and Florida Today the docking will take place at 20:14 UT 
    on Tuesday August 8th.

    Prior to docking, at 4:00 EDT (08:00 UT 8/8) there will be a visible pass 
    where the ISS will pass just north of the great lakes, over Ottawa, and 
    Boston.  From the Baltimore Washington area the ISS will be in the NNE about 
    28 deg above the horizon.  Hopefully the Progress will trail by a short 
    distance. 
    
    TiPS Question:
    Since I've been able to observe the tether on TiPS I've wondered about the 
    source of the light from the tether.  With other objects it's reflected 
    sunlight.  Since the tether is 2mm diameter acrylic yarn, am I really seeing 
    reflected light or the result of some electrical charge that is building on 
    the tether?
    
    If it is an electrical charge, then is the tether visible in eclipse?
    
    Cheers
