FCSS J033728.8-352708 is a peculiar object, measuring only 15 x 8 arcseconds, near the center of this galaxy field in Fornax.  FCSS stands for Fornax Cluster Spectroscopic Survey.  However, with a redshift of 0.08, it is not a member of the Fornax galaxy group.  Its estimated distance is around one billion lightyears !  Unlike other faint background galaxies this object displays an irregular shape and emits very strongly in blue light.  It is most probably a Luminous Blue Compact type galaxy (LBCG).  These are dwarf galaxies with very high star creation activity, that emit strongly in the ultraviolet, violet and blue.    Thanks to Mischa Schirmer for supplying the background data on this surprising little object.

The field of view is about 9.4 arcminutes wide with north towards the 2 o'clock position.
