Images of the lunar nearside obtained by telescopes of Maidanak Observatory (Uzbekistan) and Simeiz Observatory (Crimea, Ukraine) equipped with Canon CMOS cameras and Sony CCD LineScan camera were used to study photometric properties of the lunar nearside in several spectral bands. A wide range of lunar phase angles was covered, and the method of phase(More)
[1] The shadow-hiding and coherent backscattering enhancement mechanisms are considered to be the major contributors to the brightness opposition effect of the Moon. However, the actual proportions of the mechanisms at different phase angles still remain not well determined. In order to assess the lunar phase function across small phase angles, we utilize(More)

Data of 23-years of Jupiter polarimetric observations (19812004) have been reprocessed using new improved technique. The data from other observers have been added to the analysis (1971-74). An anticorrelation between asymmetry of polarization and insolation has been found. The mechanism of influence of seasons’ changing (through temperature variations) on(More)
The phase function is a measure of the light-scattered intensity, or radiance, as a function of scattering angle θ. A phase ratio is the ratio of two values of the phase function measured at different scattering angles and relates to the slope of the phase function. By taking the ratio of two images acquired at different illumination or observation(More)
Data of observations (1981-1998) have been reprocessed using new improved technique. The data from other observers have been added to the anal­ ysis. Anticorrelation between asymmetry of polariza­ tion and insolation has been found. The mechanism of influence of seasons’ changing (through temperature variations) on north-south asymmetry of polarization(More)
Lunar images acquired at non-zero phase angles show brightness variations caused by both albedo heterogeneities and local topographic slopes of the surface. To distinguish between these two factors, altimetry measurements or photoclinometry data can be used. The distinction is especially important for imagery of phase-function parameters of the Moon. The(More)
Introduction: Attempts to use the Moon as a photometric standard for calibration of spectral observations of planets and the Earth’s surface from the space were done many times. In particular integral observations of the Moon were used for this aim. We suggest here a recalibration of previous integral data including telescope and Clementine measurements.(More)
