    Thanks to everyone who replied to my message about elsets for Sputnik 1 and 
    the R-7 rocket.
    I have another question.  When working out the brightness of the payload and 
    rocket I calculated that the payload would be around mag 6 and the rocket 
    mag 0 (based on 50% phase at 500km range).  I would be interested to learn 
    from anyone who may have seen them what the brightness of each object 
    actually was.
    Thanks in advance,
