How would you like to get a heads up that the International Space Station (ISS) is going to pass over your location so you can go outside, weather permitting of course, to watch it fly over head?

Well there is a Twitter account, @twisst, that will do just that.

Of course this is all location driven so you must have your city name or coordinates in the Location block of your Twitter profile otherwise @twisst will not know where your at to figure out overhead passes. Being No Where or Out to Lunch will not work :-)

Once you follow @twisst you will get alerts a few hours ahead of a pass that look like this:

@WinObs A very bright ISS will cross your sky tonight. It comes up in the West at 9:39 pm. Details: than a minute ago via API

When you click that link it will take you to a web page with more details about the pass:


Just for your awareness – the lower the magnitude number the brighter ISS will be. The degree indication is how high off the horizon the ISS will pass. 90 degrees is directly overhead and 0 is the horizon.

I think you will enjoy this service if you like the ability to go outside and see such a large man made object that orbits the Earth at 17,500 miles per hour and completes each orbit in 90 minutes.

It is an amazing feat of human engineering and should be enjoyed.
