You can plot the position of any satellite, including the ISS, for any timeframe & vantage point, using this NASA developed Java applet:

Check out the SkyTrack!

Good luck!

My favorite site for checking satellite passes is Heavens Above:

http://heavens-above.com/

You enter your location from a map, from a database, or by latitude and longitude. While it doesn't feature sky charts, it does include the predicted brightness of the ISS or any other satellite, including the Hubble telescope and the lost ISS toolbag.

Binoculars are not needed to see the ISS, and it's sometimes visible in full daylight, as are some other satellites (Iridium flares). Information about these daylight appearances is also available from Heavens Above.

Once launched into space from Kennedy Space Center and 220 miles later is when we would be surrounded by the ISS. NASA Skywatch is an internet tool that uses five tabs to calculate when and where it can be viewed. The Skywatch applet then determines when the space craft and satelities are above the horizon for viewing. The nightime sky has to be very clear for the ISS to be seen and can be one of the brightest objects that we will ever see. Most often mistaken for a star. This site has information on how to caculate from your location to the ISS for viewing. http://www.nasa.gov/vision/space/travelinginspace/f_skywatch.html. So it really depends on your location as to what direction we need to look in for viewing the ISS.

This is the kind of question that is great for WolframAlpha. (As it's pure mathmatical input.)

Try typing: "ISS" & "Today" into wolframalpha...
http://www06.wolframalpha.com/input/?i=ISS+today

You can do this with all kind of things. Typing in Mars will show you where in the sky to see Mars tonight.
