Irregular or Lenticular Galaxy UGCA 92 (EGB 0427+63, PCG 15439),
type Irr or S0,
Discovered 1974 by P.N. Nilson.
This irregular or lenticular galaxy was suggested as Local Group candidate
by Hoessel et.al (1988). On the other hand,
Kraan-Korteweg and Tammann (1979) list it as a probable
member of the Maffei 1 - IC 342 group of galaxies; its angular separation from
IC 342 is just 6.4 degrees.
According to van dan Bergh (1994), its membership is still
uncertain, and it may be situated intermediately between both groups of
galaxies. Mateo (1998) has it as a group member and
gives a distance which, adjusted to our scale, is about 4.7 million
light-years. A membership is supported by its small redshift; it is receding
from us at only 66 km/sec.

UGCA 92 lies close to NGC 1569 in the sky, and has
approximately the same recession velocity. This implies that this Local Group
candidate might be associated with that galaxy.
Both are situated approximately in the direction of the Maffei 1 and the M81
groups, so that their role in past Local Group and Maffei 1 group dynamics may
