Stellar occultations are popular events for amateur astronomers who want to make real scientific contributions. They have traditionally been observed by travelling to a location where an occultation will be visible and timing the moments when the star vanishes and reappears. This is usually done by means of a speaking clock service, or some other audible time signal, and a tape recorder. Shortly before the occultation begins, the observer turns on the time signal, and begins recording it with the tape recorder. The observer speaks into the microphone when the star blinks out, and then speaks again when it reappears. This captures an accurate record of the times when the asteroid (or other body) passed in front of the star, and the duration of the occultation.
