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 (2.15 μ m) 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 ($R_{\rm MAX} \approx$ 15 fraction of minute55, $R_{\rm MIN} > $ 22 fraction of minute5) however, could not be traced. We assume that the flare star is enshrouded in a dust cloud of $A_{V}> 10^{\rm m}$. 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 $1600\pm400$ pc and that of the foreground extinction $A_{V} = 2\pm0.5$ mag.
