(Coma very diffuse, no tail. Low alt [17°]. Zodiacal light interference.)

(Coma very diffuse, no tail. Altitude 20°. Windy conditions, zodiacal light interference, observed from 1240m alt.)
2013  7  3.37   S 13.9 AU  25.0L  83  0.4  0/           WYA  Walcha, NSW
(Coma very small and difficult to observe due to interference from Zodiacal light. Observed over 25
minute period, motion checked, averted vision in good seeing. Also used magnification of x167 which
showed the coma only fleetingly, x83 seemed to show the coma better in periods of good seeing.)

(Difficult observation. Comet involved with two stars of 13th and 14th magn.)
2008  4 12.17   S 11.4 TK  20.3T 100  2.5  2            GON  San Mamés de Campos, Palencia
(Nearby field stars checked in DSS. Motion checked during a 60-min period. Faint outer coma is
difficult to observe with higher magnifications. Limiting star magnitude near comet : 14.5 [HN].
Rural location, very clear sky. Altitude: 32 deg.)
2008  4  6.18   S 11.3 TK  20.3T 100  2.8  2            GON  Sierra del Aramo, Asturias
(Nearby field stars checked in DSS. Motion checked during a 50-min period. Faint, diffuse outer
coma, slightly enhanced through Swan Band filter. Limiting star magnitude near comet : 14.5 [HN].
Mountain location, very clear sky. Altitude: 28 deg.)
