2015 Oct. 03.41 UT: m1=12.9, Dia.=1’, DC=1/2; 25-cm L f:5 (83x); Chris Wyatt (Walcha, NSW, Australia) [Coma very diffuse, very weakly condensed. No tail. Low altitude = 17.4°]

C/2013 US10 (Catalina)
2015 Oct. 09.39 UT: m1= 6.9, Dia.=10.5’, DC= 5/; 7×50 B; Chris Wyatt (Walcha, NSW, Australia) [Low altitude = 15.5°. Outer coma diffuse, inner coma opaque with compact central condensation, sometimes stellar. Centre enhances strongly in Swan Band filter, no tail. Tail visible in 10” f/5 dob at x39, 11.5’ of tail length opaque and fades with a (transparent) traceable length of 58’ in PA: 136°]
2015 Oct. 08.35 UT: m1=6.9, Dia.=4.8′, DC=4; 11×70 B; Con Stoitsis (Caulfield, Australia) [Comet approx 18 degrees above the horizon]
2015 Oct. 06.96 UT: m1=6.5, Dia.=12′, DC=4; 7×50 B; Marco Antonio Coelho Goiato (Araçatuba, Brazil)
2015 Oct. 05.94 UT: m1=6.5, Dia.=12′, DC=4/; 7×50 B; Marco Antonio Coelho Goiato (Araçatuba, Brazil)
2015 Oct. 05.39 UT: m1=7.0, Dia.=6.5’, DC=4; 11×70 B; Chris Wyatt (Walcha, NSW, Australia) [No tail, close to mag 8.0 star, 4.1’ away in P.A. 162°; Sky slightly hazy. Low altitude = 19.1°; Faint transparent outer coma, opaque inner coma. Through 10” f/5 dob the tail extension 8.3’ in length in P.A. 132° is opaque and fades to a transparent tail tracing out to to 40’ in length in same PA]
2015 Oct. 03.38 UT: m1=7.1, Dia.=9’, DC=6; 11×70 B; Chris Wyatt (Walcha, NSW, Australia) [No tail, close to mag 8.6 star, 8.5’ away in P.A. 116°; Outer coma transparent and faint, inner coma disc-like and opaque with small stellar central condensation. Enhances well in Swan Band filter. Through the 10” f/5 dob a x39 there is a tail visible which was traced to 27’ in length approximately in P.A. 133°. Curiously there was a faint smudge around 3’ in width, 29.5’ from the coma centre in P.A. 133°, which may be part of the tail (DE?)]
2015 Oct. 02.93 UT: m1=6.5, Dia.=10´, DC=4; 10×50 B; Willian Souza (Maresias, Brazil)
