UBVRI observations of the flickering of the dwarf nova RX And

Zamanov, R. K.; Nikolov, G.; Georgieva, A. T.

We report observations of the flickering variability of the dwarf nova RX And in five bands (UBVRI) on two nights. On 25 October 2019 the brightness of the star was B≈ 13.8 mag, the amplitude of the flickering was 0.47 mag, and we estimate for the flickering source temperature T_fl = 10700 ± 400 K, and radius R_fl =0.046 ± 0.00…
