ABSTRACT:

	A radio heliograph to obtain images of the sun in the frequency
	range 40-150 MHz and a digital spectrograph to obtain continuum
	spectra in the frequency range 30 to 80 MHz are operating at the
	Gauribidanur Radio Observatory,India.Brief description of these
	instruments,methods of image formation and registering spectra
	will be presented.

	Observations of Coronal Mass Ejections and their association
	with other solar phenomena with these instruments will be
	discussed.The results of measurements on the electron densities
	and velocities of CMEs close to the sun will also be presented.
