Multicolor photometry of features on the disk of Jupiter. I - Relative spectrophotometry in the 1977-1978 observing period

Results are presented of a study of features on the disk of Jupiter (NTrZ, NEB, EZ, SEB, and STrZ) in the fall and winter of 1977-1978. It is found that the north tropical zone was the brightest feature on the disk at all wavelengths. The relative reflecting power of the NTrZ and STrZ in the UV spectral range was less in September 1977 than it was in February 1978. During the entire observing period, there were practically no changes in the spectral energy distribution of the equatorial zone.
