Orbital determination of an asteroid (or any other body in the solar system) requires observations of its position in the sky at least three separate times.
On the first full day of the program, students are organized into teams of three and taught how to select an appropriate near-earth asteroid to observe.
They write an "observing proposal" similar to what an astronomer would submit to an observatory.
By the third night, teams begin regular nighttime observing runs, accompanied by a teaching assistant. The telescope and camera are controlled by The Sky X Professional software, generously donated by Software Bisque.
