The blazar 1156+295 was active at gamma-ray energies, exhibiting threeprominent flares during the year 2010. Here, we present results using thecombination of broadband (X-ray through mm single dish) monitoring data andradio band imaging data at 43 GHz on the connection of gamma-ray events to theejections of superluminal components and other changes in the jet of 1156+295.The kinematics of the jet over the interval 2007.0-2012.5 using 43 GHz VeryLong Baseline Array observations, reveal the presence of four moving and onestationary component in the inner region of the blazar jet. The propagation ofthe third and fourth components in the jet corresponds closely in time to theactive phase of the source in gamma rays. We briefly discuss the implicationsof the structural changes in the jet for the mechanism of gamma-ray productionduring bright flares. To localise the gamma-ray emission site in the blazar, weperformed the correlation analysis between the 43 GHz radio core and thegamma-ray light curve. The time lag obtained from the correlation constrainsthe gamma-ray emitting region in the parsec-scale jet.
