A Variable Radio-Quiet Compact Galaxy I ZW 1727 + 50


The continuous energy distributions of two Zwicky compact galaxies, I Zw 1727 + 50 and 3C 120, have been measured. The first of these is variable both in brightness and color. In I Zw 1727 + 50 nonthermal radiation probably contributes to the visual radiation, but the flux does not continue to increase in the infrared. Reasons for this behavior are discussed.
