Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

Also catalogued as VV 609, this galaxy is described by Barbieri et al. from careful examination of photographic plates as follows: "Slightly elongated dense core with gaussian profile extending up to a faint diffuse condensation 22 arcseconds away in a halo with extension to north west and somewhat denser in southern part."

p 567, Table 2: Photographic Observations, apparent major axis in arcseconds = 17.

(Sulentic and Tifft 1973) notes that this is a 14.0 mag galaxy. Their coded description reads IRR,BM,SLDIF.
