  We present BVR light curves of pulsating stars, ST Boo and RR Leo, obtained
between March and September 2007 at the Ankara University Observatory (AUG) and
the T\"{U}B{\.I}TAK National Observatory (TUG). Although these observational
data are insufficient to obtain the reliable results for a frequency analysis
of ST Boo and RR Leo stars, in this study, we tried to investigate the
pulsation phenomena of these two stars, as an overview, using the Period04
software package. As preliminary results, we present the possible frequencies
for ST Boo and RR Leo.
