This is one of the last visible passes of the Space Station before it switches to its sequence of early morning visible passes.

It's an early pass, about a half hour after sunset (the sky will still be fairly bright). The Space Station crosses the SOUTHWESTERN sky about 8:25 p.m., coming out of the WEST, just under the star, Arcturus, and heading SOUTHEAST.  It will look like a bright star, moving steadily along.  Airplanes have flashing lights, the space station shines steadily.  

Its maximum altitude will be 34 degrees up in the SW, which is just below the midway (45 deg)point  between horizon (zero deg.) and overhead (90 deg.).  If you are north of Avonport it will be lower, south of Avonport it is higher,( e.g. in Sydney it is 21 deg, in Yarmouth it is 49 deg). When at its highest in our sky, ISS is overhead near Cape Cod.  Actual speed is about 7 km per sec. at about 380 km above Earth. Because it is within a half hour of sunset, it will get almost all the way across the sky before it disappears in Earth's shadow.

If you take this link http://web.mac.com/sherm39/Site/HeavensAboveLink.html you can select a place nearest your location. The link shows a diagram of Earth showing the current position of ISS at the time you make the link. Now  click on ISS under Satellites and up comes the current schedule of visible passes.  Especially note the Time and altidude and direction of the Max. part of the pass.

Clicking on the date in the current part of the schedule gives a star map with the ISS track across the sky.  At this point you can also get a map showing the Ground Track (places on the ground that would see the ISS go directly overhead).

Currently there is a crew of 6 onboard the station http://www.nasa.gov/mission_pages/station/main/index.html

Cheers.
