In the last issue of Astropis (143/2024) – a popular Czech astronomy magazine – an article dedicated to the experimental spectroscopy of comet C/2023 (Tsuchinshan-ATLAS) was published. The observations with the Perek 2-m telescope at the ASU Ondřejov Observatory were carried out by colleagues from the Stellar Department, Pavol Gajdos (scientist, observer) and Radek Novotny (technician, observer).
In October 2024, the bright comet C/2023 A3 (Tsuchinshan-ATLAS) certainly caught the attention of all astronomy enthusiasts. It is a long-period comet (with an orbital period in the hundreds of thousands of years) that is believed to have arrived in the inner Solar System from the Oort Cloud for the first time. It was discovered on 22 February 2023 by the ATLAS survey. It came to us along a retrograde orbit with an inclination of nearly 140°. It passed through perihelion on September 27, 2024, and came closest to Earth on October. It was then visible to the naked eye for two weeks shortly after sunset.
