Juan José González (Peñausende, alt. 850 m, Zamora, España) [Objeto MAT01 de la NEOCP, situado en buen acuerdo con las efemérides de Nakano. Más brillante que lo esperado. Estrellas de campo comprobadas en el DSS. Crepúsculo astronómico. Altura sobre el horizonte: 13º]
2015 Aug. 10.35 UT: m1=11.5, Dia.=2.3’, DC=4... 25cm L f:5 (39x)... Chris Wyatt (Walcha, NSW, Australia) [Coma appears circular and pale blue in colour, diffuse semi-transparent outer coma, opaque inner coma, moderately condensed centre. Enhances in Swan Band filter. Observed over 50 minute period, motion detected and calculated to an approximate rate of 6.7”/ min travelling in PA 138°. Slight interference from Zodiacal light and twilight. I first spotted the comet at 18:24 (08:24 UT) in approximate position 12h 28m 42s... +10° 19’ 20”]
