Solar Magnetic Fields in Association with Flares [chapter]

R. Michard
1971 Solar Magnetic Fields  
The association of Ha flares with photospheric magnetic field patterns is reviewed on the basis of empirical evidence. The insertion of flares in the HH and H ± patterns is described. Present data on the evolution of magnetic structures in connection with flares suggest that flares result from special trends in this evolution leading to stressed and/or 'misconnected' fields. However no sudden changes with a flare-like time scale have been definitely observed in photospheric fields.
