BV photometric observations of the flickering of the dwarf nova RX And

We report photometry of the intranight variability of the dwarf nova RX And in two bands (B and V). The observations are carried out during three nights in November-December 2022 at the 50/70~cm Schmidt telescope of the Rozhen National Astronomical Observatory. The observations indicate that the amplitude of the flickering is about 0.5 mag in B band when the star is in faint state (m_V=13.5), but it is considerably lower (less than 0.1 mag) when the star is bright (m_V=10.9). The mass accretion rate in high state is estimated to be $1.2 \times 10^{-9}$ M$_\odot$ yr$^{-1}$. Combining our data and GAIA distances we find for the mass donor in RX~And spectral type K6V-K7V. The data are available upon request from the authors.
