[Auszug] NGC4051 was observed by EXOSAT for 62 h in December 1985, achieving a three-cr detection approximately every 50 s. Figure 1 shows the X-ray light curve, summed in 1,000-s bins. Variability is chaotic, and visually reminiscent of Cygnus X-l7. The flux ranges over a factor of 10, including a ...
