We monitored CaII H and K lines (3933A and 3968A) of the HD 179949 system to study Planet Induced Emission (PIE) as an effect of star-planet interaction. We obtained high resolution spectra (R>50,000) with high signal-to-noise ratio (S/N>50 in the Ca II H and K cores) during 10 nights of observation at the McDonald Observatory. Wide band Echelle spectra covering full optical bandwidth (3,400--10,900A) were obtained using 2.7 m Harlan J. Smith Telescope located at Mt. Locke. Detailed statistical analyses performed both for H and K cores of calcium to reveal the nature of the fluctuation in the cores as due to planet induced emission. The results are consistent with the previous studies by Shkolink et al (2003, 2008), including the proposed on/off nature of the star-planet interaction. The conclusions of the analysis also include new updates on the time evolution of the HD 179949 star-planet system.
