Lowell Observatory Near-Earth Object Search (LONEOS): Begun in 1993, the LONEOS system utilizes a 0.6-meter f/1.8 Schmidt telescope in Flagstaff Arizona to discover near-Earth comets and asteroids. The telescope was acquired from Ohio Weslayan University in 1990. Using a 4K x 4K CCD detector to cover a field of view of 2.9 x 2.9 degrees, the telescope is designed to make four scans per region over the entire visible sky each month down to a limiting magnitude of about 19. In 1999-2000, the efficiency of the LONEOS program in discovering NEOs increased significantly due to upgrades to the CCD camera and data reduction software.
Didn't see this one coming did they? Wonder what the minimum size of an object they can detect is.
