Abstract
A NEW instrument, the solar magnetograph1, has been developed for measuring and recording weak photospherio magnetic fields. With it, more than 450 magnetograms showing the distribution, intensity and polarity of weak fields (greater than 0.3 gauss) on the sun have been obtained over a two-year period including the recent minimum of solar activity2. Most of the large-scale features of the magnetic pattern show a certain regularity; but there are pronounced random variations. There is also a partially resolved fluctuating fine structure showing changes of the order of 0.5 gauss in 30 min.
