Scientific paper

We present a study of a gas-rich galaxy group that lies between RA 08h55m -08h58m and DEC +13d10m - +13d40m. This region is part of the Arecibo Legacy Fast ALFA (ALFALFA) survey - a blind extragalactic 21cm survey. The galaxy population includes red spheroidal systems, blue star-forming systems, and a few galaxies that appear to be in transition. The HI gas in the group is identified with several of the group members but is also spread between them showing evidence for interactions. We explore the HI and optical properties of this region and what they tell us about the evolution of galaxies in gas-rich groups.
