The ISS, International Space Station, as crossed the sky above me right now!
ISS is just possible to see in the sky on the sunrise or sunset when is reflecting the sun light.
It travels at an average speed of 27,724 km/hour an takes 93 minutes to a complete earth orbit.
If you want to see ISS crossing your sky I recommend to install the ISS App available on Google and Apple Stores.
Here is a gif of the video I made (due the upload gif limitation this is not a perfect shot but you can see a little point in the sky moving)
