Abstract
The results of search for variable stars in the young open cluster NGC 663 are presented. Based on 32, nights of observations five new varia ble stars have been discovered. Two of them are Be stars. Another two are pulsating - most probably - RR Lyrae variables. Star designated te mporarily as upsilon 7 is a background beta Cephei star. The unambiguo us periods and more complete light curves for two eclipsing stars disc overed earlier were also obtained.
