Summary

Magnetic and photographic data covering the transit of McMath 14943 are analyzed and compared with the evolution of flare activity in the region. Several zones of concentrated flare activity are identified and found to be associated with the presence of emerging flux, sunspot motions, and sheared magnetic fields. For two flares we identify the preflare energy build-up in force-free fields as well as the relaxation of the same fields following the energy release.
