Mount Lemmon Survey

The Mount Lemmon Survey operates a 1.52-meter Cassegrain reflector telescope at an elevation of 2,800 meters in the Santa Catalina Mountains of Arizona.

The facility began operations in 1994 as part of the Catalina Sky Survey program to detect and track near-Earth objects across the solar system.

This survey contributes to international space research by sharing astronomical data with scientists and researchers from institutions worldwide for celestial object studies.

The observatory contains a specialized camera with 10,560 x 10,560 pixels at the prime focus, enabling observations across a five square degree field of view.

Researchers at Mount Lemmon Survey discovered more than 50,000 numbered minor planets, ranking among the top discoverers in the Minor Planet Center database.
