Abstract (from CDS):


Aims. We present observations with the Advanced Camera for Surveys on the Hubble Space Telescope of the nearby dwarf spheroidal galaxy KKH 22 = LEDA 2807114 in the vicinity of the massive spiral galaxy IC 342.
Methods. We derived its distance of 3.12±0.19Mpc using the tip of red giant branch (TRGB) method. We also used the 6m BTA spectroscopy to measure a heliocentric radial velocity of the globular cluster in KKH 22 to be +30±10km/s.
Results. The dSph galaxy KKH 22 has the V-band absolute magnitude of -12.19m and the central surface brightness µv,0=24.1m/arcsec2. Both the velocity and the distance of KKH 22 are consistent with the dSph galaxy being gravitationally bound to IC 342. Another nearby dIr galaxy, KKH 34, with a low heliocentric velocity of +106km/s has the TRGB distance of 7.28±0.36Mpc residing in the background with respect to the IC 342 group. KKH 34 has a surprisingly high negative peculiar velocity of -236±26km/s.
