Many places in the USA have passes coming in the next week.
These are pre-sunrise passes, mainly SSW to NE paths.

The following sample cities provide maximum elevation information
in the following format:

Date  Local time    Azimuth/Elevation  Other info

I used Heavens-above.com but satflare.com also has the pre-launch
elset.   Azimuth accuracy is about +/- 5 degrees.  I would also
increase the time uncertainty to at least five minutes.
Ten minutes may be better.  I strongly suggest verifying your local
pass conditions just in case I made a mistake.
