How to read it
Appears / Disappears give the height above the horizon (degrees) and compass direction where the ISS becomes visible and fades. Max height: 90° is straight overhead; your fist at arm's length is about 10°. Passes above 40° are the easiest to see. The ISS often fades in the middle of the sky when it enters Earth's shadow.
A pass is listed when the station is at least 10° up, lit by the Sun, and your sky is dark (Sun at least 6° below the horizon), for at least about a minute.

Watch the station's own camera: NASA ISS live camera. Follow it on the 3D tracker. Next crew and cargo flights: crewed and ISS cargo launches. For official pass alerts by email or text, use NASA's Spot the Station.
Predictions are computed in your browser from public orbital elements (CelesTrak TLEs, from NASA/US Space Force tracking data), refreshed once a day, with satellite.js. Place search: GeoNames cities and US postal codes (CC BY 4.0). They are usually accurate to about a minute but can shift after the station boosts its orbit. Weather is not considered. T-ZERO is an unofficial fan project and is not affiliated with NASA.
When can you see the ISS?
Look for a steady, bright point of light moving across the sky. The best passes are after sunset or before sunrise: the ground is dark while the station is still lit by the Sun. Times use your device’s time zone. Allow a minute on either side for prediction uncertainty, and check again as the daily orbital data is refreshed.
How do city and ZIP searches work?
Your search is matched against city and US postal-code lists bundled on this website. No location lookup is sent to a third party. “Use my location” is optional; your browser asks before sharing coordinates, and the prediction runs on your device.
Watching from orbit instead? Open the NASA ISS live camera or explore the 3D launch tracker.
