Spotting the Space Station

The ISS looks like a bright, steady star gliding across the sky in a few minutes — no blinking lights. It is only visible when it is still catching sunlight while your sky is dark, so passes cluster in the couple of hours after dusk and before dawn.

Visibility comes in streaks: the orbit precesses, so a city gets a run of evening passes for a week or two, then a quiet spell, then a run of pre-dawn passes. If nothing is listed right now, check back within a few days.
