	With the Iridium's 86 degree inclinations, areas closer to the
equator will see fewer flares because there will be fewer visible passes per
unit area.  For Iridium flares you would be best positioned very near the
poles.  If you worked at the South Pole Station you could see flares 24 hours
a day for months at a time.

	In general, the closer your latitude is to a satellite's inclination
the more passes you will have for that satellite.
