On the Absence of Extremely Fine Structure in Quiet Sun Magnetic Fields.
Abstract
Magnetograph scans made with an exploring aperture of 360 X 360 km are found to achieve an effective resolution of 500 km when the seeing is good. Both K-network and the weaker background fields resolve into elements of a constant size, about 1500 km, when measured at the half-intensity point. While velocity and brightness elements exhibit a spatial fine structure down to the 500 km observational limit, no similar fine structure (+2 gauss) is found for the magnetic fields.
