Simultaneous optical and infrared monitoring of a sample of 50 Seyfert 1 galaxies and quasars has revealed an outburst of the active galaxy Markarian 744. Cross-correlation analysis indicates that the IR lags the optical light curve by roughly one month. A simple model developed by the author can fully explain the IR variability of this object in terms of thermal dust reverberation.
