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.
Continuous data acquisition:  even cloud, rain and snow
How the sun looks like:
Quiet sun disk, active region plages, prominence and dark filaments, prominence over the limb,
Eruptions  (very good monitor of eruptions)  10-min. movie on the Web
Sunspot associated bright features, 3-min oscillation (most of the time)
Polar brightening around solar minimum period
Nishio and other: 14 events (impulsive events, M-class)
Hanaoka: 13 events (remote source)
Both came to the same conclusion,  small + large loops (parallel magnetic field configuration, or three legged structure)
Reconnection is suggested, but I interprete in different way
Dynamical features above the flaring loop, plasma cloud ejection, wavy structure
Former CESRA meeting.
Small + large loop (supply of energy from small into large)
Centrifugal force due to earth rotation is important.
Electric field due to space charge, alternative upward and downward
High density, high temperature in a weaker magnetic field is necessary for economic fusion.
Non-linearly developed phase.
