The results of the eighth series of photoelectric UBV observations of globular clusters in the Andromeda nebula M31 are reported, continuing a program begun in 1974. The observations were made on seven nights in the autumn of 1981 with the 2.6-m Shain telescope of the Crimean Astrophysical Observatory, and the 6-m telescope of the Special Astrophysical Observatory of the USSR Academy of Sciences. A table giving the measurement results for 58 objects is included. It is noted that many of the objects observed were faint and that some of them were superimposed on the bright and irregular background of the Nebula, rendering the measurements very difficult. In these cases, the background was measured on several sides of each object, with the position of the measured areas selected on photographs in such a way that the background was similar to that where the object itself was located. It is noted that 50 of the objects listed have not hitherto been measured photoelectrically in the UBV system.
