Simple LSS spectroscopy of one candidate ultra-compact X-ray binaries. Two central-wavelength settings (GRIS 600B+22 and GRIS 600RI+19), 2 OBs in total. No stringent constraints on observing conditions. Note added on 08.12.2005: User complained that for two OBs, the wrong object has been placed in the slit upon the original execution of these OBs. Affected OBs placed back in the queues; please check acquisition carefully when re-executing these.
