one of the better tools for satellite (and space station) observation
is www.heavens-above.com/

you can map satellite passes against background stars -- it is very simple.

here is a pre-tuned view set for this pass from Palo Alto, CA
(but it is very easy to adjust for *any* locale)

btw this web page is unsurpassed for spotting Iridium flares: brief events which flare to magnitude -8. The lower the magnitude, the brighter the light; so Iridium flares are brighter than Venus (-4.4), brighter than tonight's ISS (-0.7) reported able to cast shadows in a dark sky. For reference, the full moon is magnitude -12. One child observer called it "star lightning".

The Iridium events are very transient (5-8 seconds) and localized (footprint might be only 100 km wide) http://www.assa.org.au/observing/iridium/

In case you've never seen a satellite before from the ground, or live in a big city, now's your chance if you live on the west coast. The pass will go directly overhead San Francisco and then basically down highway 5 past San Diego and into Baja California. So almost anyone in California should be able to see it clearly. ISS is bright enough that if you can see the sky, you can even see it in San Francisco or LA for the most part.

Look straight up at 7:09 PM Pacific tonight. It wont be completely dark then, but ISS is bright enough. You'll probably think you're seeing an airplane.

It will appear about 7:07 near the end of the "handle" of the big Dipper and progress to a point straight over head (85 degrees up) at 7:09:40. I observed the pass last night which wasn't as good and it was right on time. Watch it when its approaching overhead, you'll see it brighten dramatically a couple of times. Those are sun glints off the solar arrays. They were very bright last night, almost doubling the brightness of the object.

A description of the pass is at:

www.heavens-above.com is a great site for figuring out what you can see from your location. Its run by the German Space Operations Agency.

ISS is now the brightest of all the satellites and the easiest to view. Tonight there will be a Soyuz capsule from the recent launch from Russia with a French cosmonaut on board. You will be looking at the home of the only 6 people living off the surface of the earth. (ISS normally has a crew of 3 but the other 3 are visiting to exchange Soyuz capsules at the station. The new group of 3 arrived today and will be leaving next week).
