Abstract We report on a new ESB source, as defined by Allenet al. (1991), with Wolf-Rayet (WR) bands in its optical spectrum. The WR bump at λλ4605-4686 is detected. The bump consists of broad HeII λ4686, NVλλ4605-4619, NIIIλλ4634-41, and possibly, CIIIλλ4647-52 emission. The narrow nebular lines are clearly discernable on our spectrum. The number of WR stars derived from the luminosity of HeIIλ4686 is about 8100. The oxygen abundance is about 9.06×10−4, greater than the solar value.
