We report the discovery of a new conspicuous flare star coincident with the position of the IRAS PSC source 18456-0223 that is located in or projected on a dark cloud. In the immediate vicinity of the source, a very faint nebula and a small group of stars are detected in the optical. We carried out rough red band photometry and accurate astrometry of those stellar objects. In addition, near-infrared images were obtained with the DENIS survey instrument in I (0.8), J (1.25) and K_s (2.15µm) that show an increasing number of stars which appear to constitute a small cluster around the position of the IRAS source; the flare star itself (R_MAX≃15.55', R_MIN>22.5') however, could not be traced. We assume that the flare star is enshrouded in a dust cloud of A_V>10^m. By using a K vs. J-K diagram we were able to detect a new star forming region around IRAS 18456-0223 by identifying a number of YSO candidates. The distance estimate is 1600±400pc and that of the foreground extinction A_V=2±0.5mag.
