This is a brief clip showing the International Space Station transiting the moon (think: photobomb!).  The ISS is close enough to Earth's surface that it only appeared in front of the moon for people in a pretty narrow strip - just a few miles across - and it moves quickly enough in its orbit that it took just about a second to cover the moon's entire half-degree angular diameter.  

I've added arrows to help you follow the motion from right to left in this view.   Original is at https://youtu.be/RZApBpHwrUs

Footage was collected using an eVscope from Foothill College lot 4, next to the Foothill College Observatory.
