We report the analysis of the young star clusters NGC 1960 , NGC 2453 and NGC 2384 observed in the J ( 1.12 \mu m ) , H ( 1.65 \mu m ) and K ^ { { } ^ { \prime } } ( 2.2 \mu m ) bands .
Estimates of reddening , distance and age as E ( B - V ) = 0.25 , d = 1380 pc and t = 31.6 to 125 Myr for NGC 1960 , E ( B - V ) = 0.47 , d = 3311 pc and t = 40 to 200 Myr for NGC 2453 and E ( B - V ) = 0.25 , d = 3162 pc and t = 55 to 125 Myr for NGC 2384 have been obtained .
Also , we have extended the color–magnitude diagrams of these clusters to the fainter end and thus extended the luminosity functions to fainter magnitudes .
The evolution of the main sequence and luminosity functions of these clusters have been compared with themselves as well as Lyngå 2 and NGC 1582 .
