Tonight I was glancing through my Twitter account and read a tweet from the local newspaper. It said that the International Space Station was going be fly over this afternoon. I clicked on the link they included which took me to more information. It turned out that the ISS was going to pass by just 2 minutes after I saw the post.
I called up some friends in town whom I knew would appreciate knowing about it and then we all stepped outside. It was exciting to see the ISS for such a long time in the sky. It was probably visible for 4 minutes. I have seen satellites before but they are always hard to spot and only at night. We saw the ISS while it was dusk outside.
If you want to find out when the ISS is visible at your location you can look up your country/city at their website.
