SPECTROSCOPIC MONITORING OF ACTIVE GALACTIC NUCLEI FROM CTIO .2. IC-4329A, ESO-141-G55, ARAKELIAN-120, AND FAIRALL-9

The results of an intensive monitoring campaign on the Seyfert 1 galax ies IC 4329A and ESO 141-G55 are presented. Variability was detected i n both continuum and broad emission line fluxes, and the cross-correla tion analysis indicates that the most likely delay between the variati ons of the 6225 Angstrom continuum and the response of the H beta and H alpha emission lines for IC 4329A is similar to 15-25 days. For ESO 141-G55, the time-series analysis was inconclusive, and we could not o btain a clear cross-correlation signal between the lines and continuum light curves. We also present new data obtained for AKN 120 and Faira ll 9, consisting of two sets of optical spectra taken similar to 4 mon ths apart. Both objects underwent not only significant flux variabilit y (by up to a factor of similar to 2) in this interval but also strong H alpha and H beta profile variations.
