Tonight, the International Space Station (ISS) will be visible for about 6 minutes starting at 9:25PM, appearing in the northwest, moving directly overhead to a maximum elevation of 89 degrees, and disappearing in the southeast. Skies are expected to be very clear, with 11% cloud cover. The ISS circles the Earth every 90 minutes or so, but its visibility varies. You can check Spot the Station to find when and where it will be visible and sign up for alerts of when it’s most visible in your location.
