Observations have been made before and after a large solar flare. Magnetic features were observed that could be used to predict flares it they are a regular feature of such events. The observations were among the first to show the development of shear within one hour of flare onset. Observations of linear polarization have been made of transient brightenings at small points in the lower chromosphere. The association between these flare-like events and magnetic fields has been studied. A feasibility study has been made of observing the sun with a balloon-borne vector magnetograph. The APL vector magnetograph developed under an OSR URI is operational.
