Spot The Station will give you a list of upcoming space station sighting opportunities for your location.
Several times a week, Mission Control at NASA’s Johnson Space Center in Houston, TX, determines sighting opportunities for over 6,700 locations worldwide. If your specific city or town isn’t listed, pick one that is fairly close to you. The space station is visible for a long distance around each of the listed locations.
To look up viewing times for any location on Earth for the ISS and dozens of other satellites, please use SkyWatch or Gpredict.
“ SpotTheStation! Time: Wed Apr 25 7:45 PM, Visible: 4 min, Max Height: 66 degrees, Appears: WSW, Disappears NE. ”
Time is when the sighting opportunity will begin in your local time zone. All sightings will occur within a few hours before or after sunrise or sunset. This is the optimum viewing period as the sun reflects off the space station and contrasts against the darker sky.
Visible is the maximum time period the space station is visible before crossing back below the horizon.
Max Height is measured in degrees (also known as elevation). It represents the height of the space station from the horizon in the night sky. The horizon is at zero degrees, and directly overhead is ninety degrees. If you hold your fist at arm’s length and place your fist resting on the horizon, the top will be about 10 degrees.
Appears is the location in the sky where the station will be visible first. This value, like maximum height, also is measured in degrees from the horizon. The letters represent compass directions -- N is north, WNW is west by northwest, and so on.
Disappears represents where in the night sky the International Space Station will leave your field of view.
Important: The International Space Station orbits with an inclination of 51.6 degrees. This means that, as it orbits, the farthest north and south of the Equator it will ever go is 51.6 degrees latitude. If you live north or south of 51.6 degrees, the ISS will never go directly over your head- this includes places like Alaska. Spot the Station may not properly inform you of all visible space station passes in these locations. Spot The Station’s location pages will give you a list of all possible space station sightings for your location.
