Scientific paper

The statistical characteristics of atmospheric background brightness and star background density were determined in the equatorial region of the celestial sphere. Such data can be used in stipulating requirements on planned artificial satellites and in programming observations of faint astronomical objects. The basis of the statistical research method is modeling of m(back) (atmospheric background brightness) or N (total number of stars) in each j-th circle of declination of the surveyed region and determination of the parameter K (the number points in the entire region at which the brightness of the atmospheric background or star background density assumes the i-th value from a series of stipulated values). It was found that the dynamics of changes in brightness m(back) as a function of lunar phase a virtually identical character during all seasons of the year with a variation delta m(back) or = 0m.7. This makes it possible to evaluate the need for using special methods and instrumentation for ensuring the required penetrability.
