Abstract

On the basis of numerous visual estimates of integral brightness of two comets Hale-Bopp (C/1995 01) and Hyakutake (С/1996 B2) their eight curves are built in the coordinates r, m – 5 lg(D), where r – heliocentrical distance of the comet, m – a visible magnitude, D – geocentrical distance of the comet. The calculated photometric parameters of the light curves of the comets: Hy – the absolute magnitude, n – the index of the degree of r. Find out the connection between fluctuations of the comet brightness and the indexes of geomagnetic activity C9, Cp.
