2018 CL is a small near-Earth asteroid,[2] and the first confirmed finding, detected on 5 February 2018, announced on 8 February 2018, of the Zwicky Transient Facility (ZTF) project.[1][3]

The Zwicky Transient Facility is a wide-field sky survey using a new camera attached to the Samuel Oschin Telescope at the Palomar Observatory. The Zwicky Transient Facility is designed to detect transient objects that rapidly change in brightness, for example supernova, gamma ray bursts, and collision between two neutron stars, and moving objects like comets and asteroids. The new camera is made up of 16 CCDs of 6000×6000 pixels each, enabling each exposure to cover an area of 47 square degrees. The Zwicky Transient Facility will be capable of imaging the entire northern sky in three nights and scanning the plane of the Milky Way twice each night to a limiting magnitude of 20.5. First light was recorded of an area in the constellation Orion on November 1, 2017.[4][5][6]
