Abstract
IT is reported from the McDonald Observatory, Texas, that a new satellite of magnitude 17 to the planet Uranus was found on a plate taken on February 15, at the Cassegrain focus of the 82-in. telescope. Two other plates taken on March 1 confirmed the new discovery. Its distance from the planet is about 0.00082 astronomical unit, or 76,500 miles, which implies that its period of revolution is about 31 hours.
