The International AGN Watch
Welcome to the AGN Watch Website
The AGN Watch is a consortium of astronomers who have studied the
inner structure of active galactic nuclei (AGNs) through
continuum and emission-line variability. As a group, we have
carried out large-scale multiwavelength monitoring programs using
both space-based and ground-based facilities.
At the present time, the AGN Watch has completed all of its
projects and is now inactive.
AGN Watch data are intended to be available to anyone who
is interested in studying AGN variability. At the present
time, nearly all our published light curves and spectra
(from IUE, HST, and ground-based telescopes) are available
to download from this site.

Revised version of 13-year optical continuum light curve
(18 observations from 1993 were missing from the original.
Thanks to Charles Kuehn for calling this to our attention.
