Abstract (from CDS):

We present HST WFPC2 and ground-based images of the low surface brightness dwarf Irr/Sph galaxy KKR 25 in Draco. Its colour-magnitude diagram shows red giant branch stars with the tip at I=22.32mag, and the presence of some blue stars. The derived true distance modulus, 26.35mag±0.14mag, corresponds to linear distances of KKR 25 from the Milky Way and from the Local Group centroid of 1.86 and 1.79Mpc, respectively. The absolute magnitude of the galaxy, MV=-10.48, its linear diameter (0.54Kpc) and central surface brightness (Σ0,V=24.0mag±0.2mag/"2) are typical of other dIrr/dSphs in the Local Group. Being situated just beyond the radius of the zero-velocity surface of the Local Group, KKR 25 moves away from the LG centroid at a velocity of VLG=+72km/s.
