120 GeV [@Alber06]. The differential energy spectrum (d$\Phi$/dE=f$_0$ E$^{-\Gamma}$), with power law index ($\Gamma$) of 3.0$\pm$0.4, was also reported by the $MAGIC$ group. In May 2006, 1ES 1218+304 was the target of $HESS$ (High Energy Stereoscopic System) observation campaign and these observations did not yield any statistically significant signal from the source [@hess08]. The corresponding 99.9$\%$ Confidence Level (CL) limit on integral flux above 1 TeV was reported to be 17$\%$ of the $HESS$ Crab Nebula flux. The $STACEE$ (Solar Tower Atmospheric Cherenkov Effect Experiment) detector monitored 1ES 1218+304 during 2006-2007 above 160 GeV but did not detect any significant $\gamma$–ray emission from the source [@Stace11]. In 2007, $VERITAS$ (Very Energetic Radiation Imaging Telescope Array System) telescope observed VHE emission above 160 GeV from the source at a persistent level of 6$\%$ of the Crab Nebula flux [@Accia09]. The differential energy spectrum of the source was found to be compatible with a power law of index 3.08$\pm$0.34. Using the lower limit EBL from galaxy counts [@MP00; @Faz04], the intrinsic power law index was found to be 2.32$\pm$0.37. During the December 2008 - May 2009 monitoring campaign of 1ES 1218+304, $VERITAS$ telescope revealed a prominent flaring activity from the source at
