Trumpler 24 is a comparatively poorly-studied young open cluster. To investigate the correlation between the Be phenomenon and the cluster age, and to study the stellar variability in Trumpler 24, CCD time-series observations were made in 2001, and spectra were obtained in 2002. The results reveal 21 new variable stars, including 3 eclipsing binaries, no Be stars.
