    Hi Robert
    
    From my obs this afternoon , Atlantis was on time , but passed further down 
    the Suns disk than expected.In fact I almost missed it completely.
    
    However , I did manage to catch a few frames , which I'm checking at the 
    moment.
    
    From your point of view , in a dark sky , you'll hardly notice the slight 
    variation in track.
    
    John
