    I would like you to forward this to SeaSat L.  I can also remember
    during 
    this time you had Skylab which had an orbit like the ISS today.  Around
    the 
    time of the summer solstice in June 1973 Skylab stayed in sunlight all
    the 
    time.  This would happen when Skylab reached its most northerly part of
    its 
    orbit when it was around 1:00 AM local daylight saving time.  Then it
    was 
    empty.  When it was occupied by men in the middle of January 1974 there
    was 
    another period when Skylab stayed in sunlight all the time.  Then it
    reached 
    its most southerly part of its orbit when it was around 1:00 AM local 
    daylight saving time.  At that time it was not be visible from Seattle 
    because all the passes were in daylight as they would tend to center on
    1:00 
    PM local daylight saving time over a period of just over six hours.  In
    June 
    1973 they centered on 1:00 AM local daylight saving time and would all
    be in 
    darkness.  In the winter the lower orbit of Skylab meant that passes
    could 
    not be seen more that two hours and fifteen minutes before sunrise or
    two 
    hours and fifteen minutes after sunset.
    
    Sincerely,
    
    Gary Peterson
