	First, about Nobeyama Radioheliograph instrument, its characteristics

	Then introduction how the Sun looks like at 17 GHz
	Quiet sun, active region

	Most of the time is spend on flare observations: summaries of observations
	By the Nobeyama radioheliograph. Its geometry and dynamics of thermal and nonthermal flares. Oscillation studies

	To interpret the results from observations, a new solar flare scenario is proposed. Not by the reconnection scenario, but by high beta disruption or ballooning instability.
