Start in the right direction.
The pass direction tells you where to look when the ISS reaches 10° above the horizon. A closed fist at arm’s length spans roughly 10°.

Explore your sky.
Positions are calculated for your selected location and time. Potential visibility uses horizon, darkness and solar separation estimates, not weather. Includes the Sun, Moon, seven planets, six bright stars, major seasonal meteor showers, Starlink, and the ISS—not an exhaustive catalog of comets, deep-sky objects or satellites.

Look for a bright, steady point of light moving smoothly across the sky. The ISS does not blink like an airplane.
