A small, dwarf irregular galaxy, a probable Local Group member, mag 13.2. Recorded as a Palomar discovery in 1958. The image provides evidence the galaxy is relatively near by almostly completely resolving the galaxy into stars. Its status as a nearby dwarf was confirmed in 1975. Small HII regions. Luminous blue stars indicate ongoing star formation. Possibly a satellite of the Andromeda galaxy. The galaxy to its left, PGC 214961, is much further away and unrelated.
