On this page I collect my observations of the comet C/2022 E3 (ZTF).
C/2022 E3 (ZTF) is a long-period comet from the Oort cloud that was discovered by the Zwicky Transient Facility (ZTF) on 2 March 2022. The comet has a bright green glow around its nucleus, due to the effect of sunlight on diatomic carbon and cyanogen. The comet reached its perihelion on 12 January 2023, at a distance of 1.11 AU (166 million km), and the closest approach to Earth was on 1 February 2023, at a distance of 0.28 AU (42 million km). The comet reached magnitude 5 and was visible with the naked eye under moonless dark skies. As of 5 February the comet was within 6 degrees of Capella (about the field of view of common binoculars) and estimated to be about magnitude 6 (from Wikipedia, adapted).

*) Since the telescope tracks the star background, the comet gets longer during the observation time, because it moves differently than the stars.
