The below link is to NASA and will help you find sightings this week on the Shuttle and the Int. Space Station (ISS).
The dates with longer duration and higher elevation are really awesome to watch.
Just saw on the news a minute ago that the two have split, so you may see them chasing across the sky.
Sorry if you have clouds.
Check it out, find your state/city. Times are usually right on, so bring the family out for a few minutes.
I did that once during a small party and when the Shuttle showed,, they all looked at me and said, "Your were serious,,,,!"
I told them "I got connections."
