Comet C/2023 A3 (Tsuchinshan–ATLAS) was discovered by the Purple Mountain Observatory (Tsuchinshan in Chinese) in January 2023, and independently by the Asteroid Terrestrial-impact Last Alert System (ATLAS) telescope in South Africa in February 2023. A previous ADAP showed an image of the comet captured early in the morning from Geraldton during the 2024 Radio School — today’s image, taken the same day, features Murriyang, the Parkes radio telescope in the foreground. The comet passed passed within 44 million km of the Earth on 12 October and is now an evening object. (Image credit: John Sarkissian)
