Abstract:
IIA is presently involved in the expansion of its existing radioheliograph
operating in the frequency 120-40 MHz at the Gauribidanur radio
observatory located about 80 km north of Bangalore. Once completed, the
expanded array will have an angular resolution of ~1` at a typical frequency
of 100 MHz. This paper describes the development of solar radio
astronomy activities at IIA since 1952 when the first observations were carried
out.
