THE LIFETIME OF H ALPHA-STRUCTURES IN ACTIVE REGIONS ON THE SUN,
Abstract
During the last two quarters of 1966 time series of exposures of active regions on the sun were obtained at the Solar Observatory at Harestua using the Zeiss Coude refractor and a Lyot monochromator. By a graphic method the mean lifetime of 574 fibrills taken from 81 selected areas is found to be 4 hours. (Author)
