The International Occultation Timing Association is a scientific organization  promoting the observation,  prediction and analysis of lunar and asteroid occultations and solar eclipses. IOTA astronomers have organized teams of observers worldwide to travel to observe  grazing occultations of stars by the Moon, eclipses of stars by asteroids and solar eclipses since 1962.
