Abstract. We have observed two AGNs Markarian 501 (z =0.034) and 1ES2344+514 (z=0.044) in Very High Energy (VHE) γ-ray region with the TACTIC telescope located at Mt. Abu, Rajasthan. The observations on these two extragalactic sources were made during March 2010 May 2010 and November 2009 - December 2009 for 77.9 and 47.6 hours respectively. Preliminary analysis of the data does not indicate presence of a statistically signi.cant VHE gamma-ray signal from either source direction. Further, data of three satellite based experiments FERMI (30 MeV-300 GeV), RXTE (ASM 2-12 keV) and Swift (10-50 keV) on these two AGN were also analyzed to obtain respective contemporaneous source light curves in order to investigate states of these objects at lower energies as well. Details of these results will be presented in the meeting.
