Faint tail visible. Coma enhances well in Swan Band filter.) 2026 4 28.34 M 4.5:TK 25.0L 40 1.6 6 WYA Walcha, NSW (Magnitude uncertain due to Moonlight, twilight and low altitude 1.6°. Sun altitude -12.7°. I was probably only measuring the inner coma portion. The central condensation appears orange/yellow in colour, dims in Swan Band filter. The outer coma portion visible enhanced in Swan Band filter. I was able to faintly see the comet in 15x70B’s a few minutes before this observation in twilight; it appeared fuzzy and had a slight green/blue tinge, DC of 5. Telescopic observation ended when comet set in trees on the horizon. Comparison stars chosen were as near to the comet’s altitude as practicable, no extinction corrections applied.) 2026 4 19.36 aM 4.5 HD 10.0B 20 4 7/ 0.5 275 GOI Araçatuba (Comet altitude 5°, Sun altitude -12°.
