Whilst everyone is concentrating on the nucleus, now swinging towards evening skies,
I attempted to capture the dust tail in the morning sky from the southern hemisphere, with success.
C/2023 A3 Tsuchinshan-ATLAS dust tail on 2024 October 10 at 18:15UT.
using a Canon 6D + Sigma 200mm lens. 12x30sec iso3200. FOV 15deg. North lower left. from Swan Hill, Victoria, Australia. 35S 144E
This tail measures at least 45 degrees from the nucleus in PA 253 towards U Hydra (marked on image) and is made up of dust situated along the orbital plane of the comet, the "tail end" of the dust tail.
Earth crosses this orbital plane on October 15, and will result in a significant dust tail (PA 71) and anti-tail (PA249), rivalling 1957 comet Arend-Roland.
Whilst imaging this, I was interrupted by a magnificent aurora australis display happening towards the south.
