  We present infrared and radio continuum observations of S 201 star forming
region. A massive star cluster is observed in this region, which contains
different classes of young stellar objects. The near-infrared colour-colour and
colour-magnitude diagrams are studied to discuss the nature of these sources.
We have discovered the knots of molecular hydrogen emission at 2.122 micron in
the central region of S 201. These knots are clearly seen along the diffuse
emission in north-west direction which are probably the obscured Herbig-Haro
objects. High sensitivity and high resolution radio continuum images from GMRT
observations at 610 and 1280 MHz show an interesting arc-shaped structure due
to the interaction between the H II region and the adjacent molecular cloud.
The ionization front at the interface between the H II region and the molecular
cloud is clearly seen by comparing the radio, molecular hydrogen and Br Gamma
images. The emission from the carriers of Unidentified Infrared Bands in the
mid-infrared 6-9 micron (possibly due to PAHs) as extracted from the Midcourse
Space Experiment survey (at 8, 12, 14 and 21 micron) is compared with the radio
emission. The HIRES processed IRAS maps at 12, 25, 60, and 100 micron, have
also been used for comparison. The spatial distribution of the temperature and
the optical depth of the warm dust component around S 201 region, has been
generated from the mid-infrared images.
