The earlier studies of the optical environment suggested that the source could be located in a galaxy cluster or a group. However, we report a non-detection of hot gas on large scales (out to $\\sim 60$ kpc radius) and place an upper limit on the X-ray luminosity of $<3\\times10^{42}$ erg s$^{-1}$, consistent only with the presence of a poor, low-temperature ($\\rm kT < 0.5$ keV) galaxy group.
