【摘要】We carried out photometric studies of the radio-loud Narrow-line Seyfert 1 galaxy (NLS1) PKS0558-504 using both the first Antarctic Survey Telescope (AST3-1, 0.5 m aperture) located at Dome A in Antarctica and the 0.6 m Southeastern Association for Research in Astronomy (SARA) South telescope located at the Cerro Tololo Inter-American Observatory in Chile. The AST3-1 telescope is equipped with a 10K×10K single-chip CCD camera, which is one of the largest single-chip CCD cameras ever used in astronomy, and its site provides the best observation conditions on earth’s surface. The photometric data taken with AST3-1 were obtained with cousin i band during 6 nights from April 30 to May 7, 2012. In order to compare and double check the data quality, this target was imaged again using the SARA 0.6 m telescope with SDSS-g and i bands during 10 nights from October 31 to December 16, 2012. We will present detailed data analyses, the light curves obtained from both telescopes, and the mechanism for the light variability.
