Description

My image shows two comets, the currently better known comet C/2022 E3 (ZTF) and comet C/2022 U2 (ATLAS). E3 (ZTF) now shows only a faint downward gas tail and brighter dust tail. Comet C/2022 U2 (ATLAS) glows greenish between the yellow star Haedus I and the blueish-white star Haedus II. Purely by chance I discovered it on my photographs, at first I thought it was a fragment of E3 (ZTF). U2 (ATLAS) was first discovered on 25 October 2022 by ATLAS, an asteroid impact warning system of the University of Hawaii. ATLAS automatically scans the sky several times a night for moving objects. U2 (ATLAS) has already been at perihelion, the closest point to the Sun, in January, and it will visit us again in about 1000 years.
