The ultraviolet/optical variability of PG 1553+11Ultraviolet optical observations of the BL Lacertae object, PG 1553+11, indicate that significant color variations are associated with the luminosity variations seen in the ultraviolet and the optical regions of the spectrum. The color variations are consistent with the presence of an accretion disk in this system.
