The young emission-line star LkHα225 (V1318 Cyg) with a tiny cometary nebula is located in the small group of very young stars around the well-known Herbig Ae/Be star BD+40°4124. LkHα225 was discovered by Herbig (1960) and studied by several authors (see for references Ibragimov et al., 1988). The star undergoes strong variations of its light (nearly 3 magn.) in visible light as well as in infrared. Spectral type of LkHα225 is very uncertain, but its high luminosity (Lbol=460 L⊙) and mass (5.5 M⊙), as well as the presence of nebulosity suggests that it also belongs to the Herbig Ae/Be class of pre-main sequence (PMS) stars. This small and perhaps variable nebulous appendage on the NW-side of the star can be readily seen on the plates obtained with the 2.6-meter telescope of Byurakan Observatory.
