Abstract. During a campaign in December 2006, radio spectrum measure- ments over the frequency range 45-870 MHz were carried out at the Gauribida- nur observatory, located about 100 km north of Bangalore. The spectrometer used for the above purpose was subsequently configured for radio spectral ob- servations of the solar corona. This paper describes, (i) radio frequency inter- ference over some of the frequency bands `protected' for radio astronomy; and (ii) `first' solar radio burst observation and the above instrument.

Keywords: Sun : corona, solar flares - radio observations - radio frequency interference (RFI)
