    Calculations in my ancient copy of Mike McCants' QuickSat
    using the latest elset from JSC , 9012 ,
    http://spaceflight1.nasa.gov/realdata/sightings/SSapplications/Post/JavaSSOP/orbit/ISS/SVPOST.html
    suggest that the space station will not , just as Larry Wood
    suggests , be able to observe the umbral shadow of Luna .
    However , it's close enough to suggest to me that the penumbral
    shadow should be plainly visible from the combined ISS/STS-127
    about 2009-07-22 0343 .
    Cloudy , you say ?  So , who cares ?  What freedom !
    
    Cheers ,
