A cluster of three galaxies has been observed around the unusual object S5 0716+714, which displays a lineless continuum throughout all wavelength intervals (from radio to gammarays) and rapid variability (even within a day). The galaxies have very similar redshifts: 0.264 ± 0.004, 0.257 ± 0.005, and 0.249 ± 0.003. for the first time, our observations with the 6-m telescope of the Special Astrophysical Observatory equipped with the multimode SCORPIO spectral camera have revealed some evidence for the host galaxy around the object—an elliptically shaped flux excessively extended by 3″–5″ from S5 0716+714.
