Scientific paper

On the night of July 2, 2008, we used the R-C spectrograph of the CTIO 1.5m telescope in Cerro Tololo (Chile) to perform optical spectroscopy on sources inside the 90% confidence level Swift/XRT X-ray error boxes (Landi et al., ATels #1539 and #1437; see also Ibarra et al., ATel #1397) of the unidentified INTEGRAL sources IGR J17404-3655 and IGR J18173-2509 (Bird et al. 2007, ApJS, 170, 175). The optical objects were selected by overlapping the XRT error boxes on the relevant DSS-II-Red survey archive images (http://archive.eso.org/dss/dss).
