Sail on ISS!

Just watched the ISS sail south west to north east across the sky shortly after sunset at 6:36pm. It looked like a bright star moving quickly across the sky. Took roughly three minutes to zoom out of view at 18,000 MPH. Amazed. There were some kids we pointed it out too. I was tempted to say it was Santa but I wanted them to know it was the ISS. They thanked me.
