I did some predictions based upon the current ISS orbit (as of
today) and have the following "good" passes.  A good pass is where
the ISS obtains at least a 30 degree elevation above the horizon.
I also limited the passes to those between 8:30 AM and 2:30 PM -
the normal school day:

Times are in UTC - you can subtract 8 from the time to get local
time (1930 UTC is 1130 PST).

Monday 3/4: 1930-1940 - 47 degrees
            2106-2116 - 29 degrees (well, it's almost 30)

Tuesday 3/5: 1829-1840 - 32 degrees
             2005-2016 - 61 degrees

Wednesday 3/6: 1729-1739 - 29 degrees
               1905-1915 - 67 degrees
  
Thursday 3/7: 1805-1815 - 40 degrees
              1941-1951 - 37 degrees

Friday 3/8: 1704-1714 - 29 degrees
            1840-1850 - 81 degrees

Note that some of the lower orbits still might be fine.  It looks
like we still get about 10 minutes out of a pass as low as 20 
degrees.  

These could include:

    3/4: 1753-1803 - 25 degrees

    3/5: 1653-1703 - 26 degrees

    3/6: 2041-2051 - 18 degrees

    3/7: 1628-1638 - 25 degrees

    3/8: 2016-2025 - 11 degrees

As you can all see - there are LOTS of opportunites during this
week for a contact during normal school hours.  Many thanks again
to Kerry for negotiating the new schedule.  There were simply no
passes that occurred during the normal school day during the week
of January 28th.

Note that these times might shift some due to normal orbit 
corrections.  We will obviously sharpen our pencils as we
get closer.

Kerry - you might spot check one of two of these with your computer
to make sure I am not doing something wrong.
