Analysis of the solar phase curves of the Jupiter's satellite Callisto

Using long-term photoelectirc observations by author and Lockwood et al. for solar phase angles α from 0 to 12 degree we have obtained Hapke's parameters w, g, h, B of the solar phase functions for the leading and trailing hemispheres of the Jupiter's satellite Callisto. The curve, with parameters determined from the λ 0.540 μm ground-based observations in the small range of α (from 0 to 12 degree), agrees well with the total solar phase functions for both hemispheres measured in the large interval of α (from 10 to 140 degree) during space probe missions by Voyager.
