See the International Space Station (ISS) Using the Predictions Note the time, Az (azimuth), El (elevation), and visibility columns of the report. At a given time the satellite's position can be determined by its azimuth and elevation. Azimuth is the angle relative to true north (0 or 360 is north, 90 is east, 180 is south, etc.). Elevation is the angle relative to the horizon (0 is at the horizon, 90 is straight up). The satellite can be seen when the observer is in darkness and the satellite is illuminated by the sun. Satellites sometimes fire their thrusters to offset atmospheric drag. When ISS does this the predictions might be off by about 5 minutes. I will go outside with a compass about 5 minutes early and trace out the predicted path. I will then continually watch that area. I have had very good results. Jeff Stetekluh (jeff.stetekluh@acm.org)
