Inter - Network magnetic fields observed with sub - arcsec resolution

Abstract

We analyze a time sequence of Inter-Network (IN) magnetograms observed at the solar disk center. Speckle reconstruction techniques provide a good spatial resolution (0. ′′ 5 cutoff frequency) yet maintaining a fair sensitivity (some 20 G). Patches with signal above noise cover 60 % of the observed area, most of which corresponds to intergranular lanes. The… (More)
