-----------------------------------------------------------------

The pass times of ECHO repeats every 5 days.  Just cut the table 
below for your time zone.  Tape it to your dashboard and you can 
see pass times for your mobile every day for the next few months 
within about 5 minutes.

To use it on any day, just look for a column near your date.
Then move left or right the number of days to your day.  The best
morning and best evening passes are shown.  There is a pass 100 
minutes earlier and 100 minutes later than the best pass shown.

Details:  Morning passes will be a few minutes earlier in the North 
and a few minutes or so later in the South.  Evening passes will be
the reverse.  On the days when there are two passes, they are both 
low, and you won't be able to work the one before or after.  On the 
days with a single pass shown it is a very high pass and there will 
be one before to the east and one after (100 minutes) to the west.

Taking these in mind, consider your location in your time zone.
If you are on the eastern edge, then the earlier pass will be
better and the unprinted earlier pass will also be good.  To the
west of your timezone, the later passes are better.  As the months
progress, you can also shift earlier by 3 minutes per month for
best accuracy.

The tables above were generated at the center of their time zones
120, 109, 94, and 78 degrees west and about 40 degrees latitude and
for passes above 25 degrees or so.
