  We present photometric observations of transit of the exoplanet HAT-P-24b
using the Rozhen 2 m telescope. Its solution gives relative stellar radius
r_{s}=0.1304 (a/R_{s}=7.669), relative planet radius r_{p}=0.01304 and orbital
inclination of 90 degree. The calculated planet radius is R_{p}=1.316 R_{J} and
corresponds to planet density of rho_{p}=0.37 g cm^{-3}. Our parameter values
are between those of the previous two solutions. We did not find evidences of
TTV and TDV signals of HAT-P-24b.
