Quiescent solar prominences have been observed simultaneously in profile-integrated He D_3and Hβ emision with the ST on La Palma. The two-dimensional ratio maps of the He D_3arid Hβ intensities are used to study temporal variations of intrinsic prominence parameters. Sub-areas with substantial variation of the intensity distribution indicate the evolution of prominence structures. When the emission ratio remains unchanged, the evolving threads are of largely equal physical state. Other regions which show a temporal varying emission ratio indicate substancial evolution of the intrinsic physical conditions. We propose that distance variation bettween the threads affects different penetration of the EUV irradiation required for populating of the He triplet system.
