Abstract
The distribution of the sky background brightness at moonless and moonlit nights was studied with the electrophotometer in combination with the AZT-14 telescope at Abastumani Observatory. The investigation was made for blue and yellow lights.The empirical formulae (1),(2),(3),(4) were derived through which one can predict the intensity of the area of 1 square second at random in the sky when the Moon's age and the distance of this area from the Moon are known.This value may change within 1 mag at a particular night depending on the sky quality. At moonless night the intensity turn out to be 20m81 and 21?82 for yellow and blue lights respectively.
