I was out on the deck about 9pm when the ISS became visible, flying almost directly overhead. Satellites become visible as solar panels catch Sunlight and reflect it back down to Earth. They are visible just after sunset and just before sunrise. This passover was very bright and with binoculars, one could see two lobes that were the two solar-panel arrays on the ISS. Needless to say, I not only rushed to grab my binoculars, but also called my step-sons to come out and enjoy it with me. It wasn’t long before it moved into the Earth’s shadow and disappeared from view.
If you want to see an ISS flyover, you can go to this site and put in your zip code and find the local times for flyovers and where in the sky to look.
