Cool, I just saw the ISS!
The International Space Station just passed
over Seattle. It was visible 8:48 to 8:52,
heading from SW towards NE.

Then, rather suddenly, just past straight overhead,
it went dark. It is about 200 miles up,
and then passed into the shadow of the Earth.

It was some kind of satellite.
