                         successfully completed by the end of 2004. Presently, the BDA 
                         consist of 5 antennas laid over a distance of 216 meter in the E-W 
                         direction and located at a Longitude of 450\'20\{"} W and a 
                         Latitude of 2241\'19\{"} S. The array operates in any selected 
                         frequency in the range of 1.2 to 1.7 GHz, with a time resolution 
                         of 100 ms and a spatial resolution of ~3 arc minute. The operating 
                         time is from 11- 19 UT. Solar observations are carried out in 
                         transit/tracking mode. Efforts are being made to use GPS 
                         satellites for phase and amplitude calibrations. Presently, strong 
                         radio sources like Cygnus-A and Taurus-A are being used for 
                         amplitude and phase calibration respectively. In this paper we 
                         will present preliminary results of solar observations such as one 
                         dimensional brightness temperature maps of the sun at local noon 
                         and day to day variations of its brightness temperatures at a 1.6 
                         GHz. The observed brightness temperature is ~ 0.5 - 3.5 x 105 K.",
