Abstract

The light curves of four new comets: C/2000 WM1 (LINEAR), C/2001 A2 (LINEAR), C/2002 C1 (Ikeya–Zhang), C/2002 F1 (Utsunomiya), and a short-period comet 19P/Borrelly - the target of space mission “Deep Space-1”, were constructed and investigated. The values of the photometrical parameters Hy and n of these comets and the parameters of their brightness outburst activity were obtained. The stick-slip variations of the parameter n during preperihelion and postperihelion branches of light curves of comets C/2001 A2, C/2002 C1, C/2002 F1, and 19P were found. An influence of the phase dependence on the light curve of comet C/2001 A2 during preperihelion part of its orbit were found. A comparison of light curves of the short-period comet 19P during its three different appearances (1981, 1987 and 2001) were maked.
