    I've seen one or more on four occasions at 25 deg elevation and less - 
    22:00-24:00 UTC, going away to my south-east, using 10x50 binoculars 
    hand held.
    
    Aug 7 one day after launch - three objects: leader and trailer +5 and 
    +5.5 respectively, third object on the limit of visibility because of 
    thin cloud, +7.
    
    Aug 8 - four objects, +5, +5.5, +7, +7.5 but I didn't note the order.
    
    Aug 11 - one of the brighter objects spotted by chance as it passed near 
    the path of the ISS.
