The sixth column gives the direction and elevation at which the spacecraft will disappear from view. The fifth column tells the direction and elevation at which the spacecraft will become visible initially. The fourth column gives the maximum elevation the vehicle will achieve above the horizon (90 degrees is directly overhead).
The third column gives the duration, or the length of time in minutes the spacecraft is expected to be visible, assuming a clear sky. The next column is the local date and the local time. The text listing is in a column format, a sample of which is shown below: You also can sign up to receive notices of opportunities in your email inbox or cell phone. NASA operates the “Spot The Station” service to provide sighting opportunities in a text listing by city. It is bright enough that it can even be seen from the middle of a city! Typically it will be the brightest object in the night sky (except for the Moon). The space station looks like a fast-moving plane in the sky, but it will be seen as a steady – not blinking – white pinpoint of light.
Depending on your location on the Earth's surface, a spacecraft's position in orbit and the time of day, you may be able to see the International Space Station (ISS) or visiting vehicles as they orbit about 240 statute miles above the planet.
