We examine published sunspot and calcium plage areas for 1620 solar active regions between 1974 and 1985. With these data we study the properties of ensemble-averaged active regions. The average sunspot area per region, the average plage to sunspot area ratio, and the average plage intensity of regi

In order to study the temporal behavior of fine structure in the solar chromosphere, time-lapse sequences of spectroheliograms have been obtained in the violet emission peak (Kzv) of Ca II 2 3933. Figure 1 shows such a time-lapse sequence taken with the 36 cm image of the McMath Telescope at the Kit
