The 2024 Radio School is being held this week in Geraldton, WA. Participants are learning about radio observations of stars, supernova remnants, radio galaxies, and galaxy clusters, and gaining experience in hands-on reduction of data from ASKAP and MWA. However, students up early were able to appreciate another of astronomy’s wonders — a comet! 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. The comet passed perihelion, its closest approach to the Sun, on 27 September 2024 at a distance of 58 million km, and will pass within 44 million km of the Earth on 12 October.
