Abstract

A spectrum of 2MASX J20183871+4041003, the galaxy counterpart of IGR J20187+4041, was obtained on 2008 May 5 UT using DEIMOS on the Keck II telescope, covering the wavelength range 6656-9275 Å at 1.2" resolution. Seeing was ~0.5", and the nucleus was isolated using a 0.7" wide slit. Narrow (FWHM ~300 km/s) emission lines of Hα, [N II] 6583, [S II] 6716,6730, and [S III] 9068 are detected at z = 0.0144.
