Thorough investigations on the red dwarf EV Lac, YZ CMin and AD Leo indicate that transient high frequency oscillations occur during the flare event and during the quiet-star phase as well. The postulation that this is a general characteristic of the active red dwarfs is a very important task. In the frame of this consideration we present in this paper the results of the analysis of the B-light curve for a rather weak flare of the red dwarf UV Cet, which were observed on October of 2001, with the help of the 30-inch Cassegrain telescope of the Stephanion Observatory. The combined use of Fractal analysis and DFT-analysis enable us to estimate the proper random noise and detect possible weak transient optical oscillations. In accordance to the results of past studies the results of the present study indicate that: (1) Transient high frequency oscillations occur during the flare event and during the pre-flare state as well (2) The Observed frequencies range between 0.0093 Hz (period 108 s) and 0.231Hz (period 4.3 s) not rigorously bounded. This result is in accordance
