From Spaceweather.com:
NEW--SIMPLE FLYBYS: Spaceweather.com has a new tool for US and Canadian
readers: Simple Satellite Flybys. Just enter your zip code and it tells you
about satellites due to fly over your area in the nights ahead. There are
hundreds of spacecraft in Earth orbit; we cut through the confusion by
narrowing the list to a half-dozen or so of the most interesting. At the
moment we're monitoring Jules Verne, the International Space Station, space
shuttle Endeavour and the Hubble Space Telescope. Please try it and,
remember, it's a new tool with room for improvement. Feedback is welcomed.
