A new galaxy near the local group in Draco

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.(m)32, and the presence of some blue stars. The derived true distance modulus, 26.(m) 35 +/- 0.(m)14, corresponds to linear distances of KKR 25 from the Milky Way and from the Local Group centroid of 1.86 and 1.79 Mpc, respectively. The absolute magnitude of the galaxy, M-V = 10.48, its linear diameter (0.54 Kpc) and central surface brightness (Sigma (0,V) = 24.(m) 0 +/- 0.(m) 2/square") 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 V-LG = +72 km s(-1).
