    Four of the galaxies here have similar spectroscopic redshifts, SDSS J155636.39+415250.5 (0.03471±0.00001, left), SDSS J155632.98+415353.2 (0.03578±0.00001, left-center), SDSS J155641.64+415246.5 (0.03450±0.00001, right-center), and SDSS J155636.87+415413.5 (0.03513±0.00002, right):

    There are other galaxies nearby with similar (spectroscopic) redshifts, so I guess this is likely a rich group or a poor cluster. It's curious that some galaxies show obvious signs of recent interaction, and one (the one on the right) may be the result of long ago merger.
