Visibility III / V
Comet C/2020 V2 (ZTF) was imaged on the first night of the 2022 August talcos. A comet on a hyperbolic orbit was discovered by the Palomar Mountain ZTF variable object search program (I41 Palomar Mountain ZTF) on November 2, 2020. The Zwicky Transient Facility (ZTF) is a wide-field search program for supernovae and other rapidly changing objects based on the Samuel Oschin telescope, a 48" Schmidt telescope and a wide-field camera. The perihelion comet arrives on 2023-05-08 2.235au from the sun. When photographing the comet, it was 4.4146au away in Ursa Major, it will be closest to 1.855au on September 17, 2023. The comet will be at its brightest between June and September 2023 at an estimated T9-10mag We have imaged this comet several times.
