PHOTOMETRIC STUDY OF THE OLD OPEN CLUSTER TOMBAUGH 2

We present the results of near-IR band (JHK) photometric study for the old open cluster To 2. Combined with existing optical data, our IR photometry is used to derive the reddening E(B- V)=0.24$\pm$0.12 and the distance (m-M)o=14.6$\pm$0.42. Comparison with theoretical isochrones suggests the age and metallicity of To 2 are log t$\~$9.3 and [Fe/H]$\~$-0.3, respectively.
