NOTICE: JPL's Center for NEO Studies (CNEOS), which operates neo.jpl.nasa.gov, will substantially upgrade the site in early 2017, giving it a new look-and-feel, improved navigation and added content. Scripts which extract data from HTML on the current site will have to be revised to use the related API on the new site. Specifics on the new APIs will be provided here a month before the site transition takes place.

The Catalina Sky Survey (CSS)
Catalina Sky Survey: The Catalina Sky Survey (CSS), based at the University of Arizona, is a very successful discovery program, an achievement that is due, in large part, to their comprehensive sky coverage, human attention to potential discovery images and on site follow-up observation capabilities. In 2012 alone, CSS discovered more than 625 NEOs. Some 20% of CSS observing time is devoted to the post-discovery, follow-up observations that allow the object's orbit to become secure.

CSS discovery telescope assets (Aperture, f number, MPC Observatory Code, field of view, pixel size):
Schmidt: 0.68-m, f/1.8, Obs. code = 703, 8.2 sq. deg., 2.5 arcsec/px
Mt. Lemmon: 1.50-m, f/2.0, Obs. code = G96, 1.2 sq. deg., 1.0 arcsec/px
Uppsala Schmidt, Australia: 0.50-m, f/3.5, Obs. code = E12, 4.2 sq. deg., 1.8 arcsec/px (This southern hemisphere program ended in 2013)

CSS follow-up telescope
Mt. Lemmon: 1.00-m, f/2.6, Obs. code = I52, 0.25 sq. deg., 1.0 arcsec/px

Through a continuous improvement program, CSS began use of the 1-m follow-up telescope in 2013 and in 2014, the Catalina Schmidt will be upgraded to a larger CCD array that will increase its field of view from 8.2 to 19.4 square degrees and the Mt. Lemmon 1.5-m will be upgraded to a larger CCD array that will increase its field of view from 1.2 to 5 square degrees.

The principal Investigator (PI) for the Catalina Sky Survey is Eric Christensen.
