The chemically peculiar star HR 4330 (=HD 96707, EP UMa) was observed using the 2-m Himalayan Chandra Telescope at the Indian Astronomical Observatory, Hanle, India, for studying the variations in its spectral features. It was found that the spectral features of CaII 3933{AA} and SrII 4077{AA} were showing rapid variations in their equivalent widths with a periodicity of 0.28+/-0.02d. Such short-term variations suggest that there could be a dynamically active surface with rapid variation in the conditions of the stellar atmosphere.
