Methane band photometry of the faded South Equatorial Belt of Jupiter

A preliminary analysis of the limb darkening curves along the unusually faint Jovian South Equatorial Belt (SEB), observed by present authors early 1990 using a CCD camera mounted on the 188 cm reflector (F/4.9 Newton focus) of the Okayama Astrophysical Observatory, is presented : three limb-darkening curves extracted from the CCD images obtained in two strong methane bands at 0.725 and 0.890 μm plus one nearby continuum region (0.750 μm) have been compared with the theoretical computations taking into account the effect of multiple light scattering
