| 内容記述 | The X-ray emitting BL Lacertae object PKS 2155-304 was observed with NRL's Large Area Sky Survey Experiment on HEAO 1 during November 10-16, 1977. Variations of a factor of 2 in the 0.5-20 keV intensity are found on time scales as short as 6 hours. Variations on time scales of 1 s, as reported by the HEAO A-2 LED experiment, are not confirmed in near-simultaneous observations. Optical spectroscopy is also presented which does not confirm the presence of previously reported redshifted (Z = 0.17) forbidden O III line emission. The question of the redshift of this object is still open. |
