摘要：

We report on the results of a 5 year coordinated program of spectroscopic monitoring of the luminous Seyfert 1 galaxy Markarian 509. The H beta and He II lambda 4686 emission lines are found to respond to continuum variations with time lags of similar to 80 and similar to 60 days, respectively, considerably longer than the emission-line lags measured for other Seyfert galaxies.
