Abstract (from CDS):

We report observations of the flickering variability of the recurrent nova RS Oph at quiescence on the basis of simultaneous observations in five bands (UBVRI). RS Oph has a flickering source with (U - B)0= -0.62±0.07, (B - V)0= 0.15±0.10 and (V - R)0= 0.25±0.05.

We find for the flickering source a temperature Tfl~ 9500±500K, and luminosity Lfl∼ 50-150L☉ (using a distance of d = 1.6kpc).

We also find that on a (U - B) versus (B - V) diagram, the flickering of the symbiotic stars differs from that of the cataclysmic variables. The possible source of the flickering is discussed.

The data are available upon request from the authors.
