## Abstract

We present here the detailed optical and infra-red photometric analysis of the open star cluster IC 361. On studying the radial density profile, radial extent of the cluster is found to be 8.0 +/- 0.5 arcmin. The basic physical parameters of the cluster such as E(B-V) = 0.56 +/- 0.10 mag, E(V-K) = 1.72+/-0.12 mag, log(Age)=9.10+/-0.05, and (m-M)0 = 12.54 +/-.05 mag are obtained using the color-color and color-magnitude diagrams. IC 361 is found to be located at a distance of 3.22 +/- 0.07 kpc. Using the archival proper motion catalogues, we estimate mean proper motions of IC 361 as 4.97+/-0.17 mas yr-1 and -5.80+/-0.18 mas yr-1 in the direction of RA and DEC, respectively. We derive the luminosity and mass functions for the cluster main sequence stars. The mass function slope is found to be -1.06+/-0.09 which is too low compare than Salpeter value.
