    If you have set your coordinates on http://www.calsky.com
    you can get predictions for Sun/Moon crossers on 
    http://www.calsky.com/cs.cgi/Satellites/16?
    
    Most other satellites are in the 1" range = 1/206000 * range
    ISS (~40m at ~400km) = 1/10000 = 20"
    
    On http://iss-transit.sourceforge.net/IssVenusTransit.html
    you can compare it to Venus at close approach (60")
    
    And just ISS+Shuttle+Sun at
