    While waiting for ISS to appear last night I noticed to the east a pair of
    satellites in trail , one a little brighter than the other.
    As I tracked them , the trailing bird started to gain on the other and
    passed it (converged to the naked eye) in spectacular fashion.
    
    I "guestimated" heights of 700 and 900 km.
    
    Looking at Calsky this morning contenders seem to be .....
