The BL Lac object PKS 1144-379.
Abstract
The highly variable radio source PKS 1144-379 has been monitored at 13 cm and 6 cm over a period of 3 years. It has been identified with an object whose photographic image is star-like. From infrared photometry, UBVRI photometry and spectroscopy, it is concluded that PKS 1144-379 is a BL Lac object with a visual magnitude approximately equal to 16.2.
