Popis: We have monitored the X-ray source X-Per (4U 0352+30) on 31 August, 1979 through aU filter for about 1.5 hr using 102-cm telescope of Kavalur observatory. During this period intensity of X-Per fluctuated for some time, on time scales of few minutes but recovered in the end. It was again monitored from 27 December, 1979 to January 1980 through a standardU, B, V photometer attached to a 34-cm telescope. In this paper we present the data on the fast flickerings observed on 31 August, 1979 and on the long term monitoring from December 1979 to January 1980.
