We present first results from an ongoing program of combining data from NRH and GMRT to produce snapshot images of the sun at meter λ. The data processing includes a superposition of complex visibilities from NRH and GMRT, a Fourier Transform and a cleaning multi-scale algorithm. We present results of a) a simulation and b) an observation of a complex noise storm at 327 MHz on August 27, 2002. This illustrates the capacity of the method to produce high dynamic range snapshot images of a complex sun, and shows that composite images are by far better than images from either instrument alone.
