    Occasionally Topex/Poseidon does very bright flares, so I wonder if 
    Jason, though it's smaller, will mimic Topex as it will be following 
    it by about 80 seconds (if I did the math correctly).  That is, 
    if Topex flares are due to its solar panel, I would think that 
    Jason's panels would flare when/if Topex does.
    We *may* get clear sky on Saturday night ... maybe ... I hope.
