Based on recessional velocity of 6670 km/sec, about 300 million light years away. Given that and apparent size of 1.0 by 0.3 arcmin, about 85 thousand light years in diameter.

The two IC numbers assigned to this object are due to Frost having taken two photographic plates of the region a few days apart, and slightly mismeasured the position of the object on each plate. There is only one object which Frost could have seen in the region, and it lies between his two measurements, so there is no doubt that the "two" objects were actually the same. Its recessional velocity of 640 km/sec is too small to provide a reliable distance indicator, because peculiar (non-Hubble expansion) velocities can be a substantial fraction of that value. Unfortunately, no redshift-independent distance estimates seem to be available, so the recessional velocity distance estimate of 28 million light years will have to do for now. Presuming that is reasonably accurate, the apparent size of 0.6 by 0.5 arcmin implies a diameter of only 5 thousand light years, hence its designation as a dwarf elliptical.
