We present a series of 18 images of the chromosphere of AR Lacertae (=HD 210334) These images were derived from Mg II k (2795 Å) spectra obtained with the IUE satellite. Three discrete plage regions can be seen on the K star, and an inactive region is visible on the G star. We also isolated a flaring region on the K star.
