Abstract
A SKYLARK rocket (SL727) carrying an X-ray astronomy experiment prepared by the Universities of Adelaide and Tasmania (UAT) was launched from Woomera in South Australia at 0030 UT on July 10, 1970. Observations of the spectrum and pulsed component of the Crab Nebula have been reported elsewhere1. This article presents the results of observations of Norma X-2. The measured flux of Norma X-2 between 2 and 10 keV is significantly higher than previous values, implying variability in the X-ray emission. The disappearance of the intense source Cetus X-2 was also established and an upper limit is determined for the flux between 1.5 and 9 keV.
