We use multiwavelength observations to identify the Young stellar objects (YSOs) and to analyze the physical conditions in a 10' x 20' square arcmin star forming complex containing three mid-infrared (MIR) bubbles N98, MWP1G047180+003195, and MWP1G047190+003200S. These bubbles appear to be connected through a filamentary molecular cloud. Integrated intensity maps in several molecular spectral lines reveal several molecular clumps distributed along the filament and associated with MIR bubbles. The spatial distribution of the candidate YSOs shows that a significant number of candidate YSOs are distributed along the periphery of the bubbles. We use the ATLASGAL continuum emission data at 870 μm to search for the dense neutral material collected on their borders. In this study, we discuss the physical conditions and star formation activity in the complex.
