Radial velocity and distance of GR8

The dwarf irregular galaxy CR8 has a radial velocity, determined from optical and radio observations, of + 227 ::::: 5 km sec-1. It contains two well-resolved Hii regions of low surface brightuess. Its distance is estimated from six different but highly uncertain arguments, from which it is concluded that probably the best estimate at present is 1.0 ::::: 0.5 Mpc. This places it just inside the local group and implies that its size is 300 pc and its absolute magnitude is Mv = -10.6. Key words: galaxy - radial velocity
