Summary:Seyfert galaxies and quasars are the most interesting objects among the different types of active galaxies as they show the continuum and line variability over a long range of wavelength and time scales. The long term observations at the UV wavelength region would be useful in understanding the possible correlations among accretion disk properties with the physical conditions in BLR regions. In this paper, we present our results on the long-term continuum and emission-line variability studies on Mrk 841, a bright nearby active galaxy using the IUE’s spectroscopic data from 1978 to 1993. The final archival data has helped us to characterise the continuum and the emission line variability observed nearly over 15 years. We have obtained Rmax values as 2.24, 2.04, 1.87, 2.28, 1.30, 2.31, 2.17, 3.59, 2.01 and Fvar (in %) parameters as 27.33, 26.34, 26.37, 26.41, 10.73, 23.00, 23.80, 41.26, 60.20 corresponding to the continuum windows centered
