Magnetogram data are analyzed to study daily variations of tilt angles of the magnetic axes of active regions defined by magnetic fields measured with the Mount Wilson magnetograph. The period covered by this daily data set is 1967 through April 9, 1990. It is found that on average regions with posi

The Mount Wilson daily magnetogram data set is used in its coarse format to determine various statistical properties of magnetic regions. The method of defining magnetic regions is described, and also the criteria for a 'return' of a magnetic region from one day to the next are given. Region sizes,
