In order to identify the nature of the active nucleus of spiral galaxy NGC 4992, associated with the Chandra and INTEGRAL high-energy sources CXOU J130905.6+113803 and IGR J13091+1137 (see Halpern, Atel #572 and Sazonov et al., 2005, A&A, 444, L37), we acquired a 15-minute optical spectrum on February 1, 2006 with the instrument BFOSC mounted on the `G.D. Cassini' 1.5m telescope of the Astronomical Observatory of Bologna located in Loiano (Italy).
