 I subscribe to a service called "Spot the Station".

This tells you when the International Space Station is visible above you.  

Of course you cannot see the space station, but what you see is the sun's reflection off the station.  Thus it has to be dark where you are, and the space station has to be in the sun's light.  

Usually, you watch it streak across the sky like a plane, but there are no blinking lights and it really moves fast.

Tonight it was very late - 10:44 pm and the text said it would come from the NW and leave to the NW.  Now this was strange as how could it leave from where it came?  And it would only be visible for 3 minutes.

So I was out there and picked it up but it seemed to be going from NW to NE.  But then it just vanished!

What had happened it the reflective light from the sun was eclipsed buy the Earth as the Space Station went around the Earth.  What was so bright was still there, just not reflecting the Sun.  

A wonderful example or proof, that the Earth is not flat. 😊

Awesome.
