Abstract
We report on a series of observations of Cyg X-2 obtained with EXOSAT in September 1983 at five phases in a single orbital cycle (P=9.8 days, see Cowleyet al. 1979). Here we present spectral data obtained with the Argon counters of the Medium Energy experiment (ME) (see Turneret al. 1981), together with the search of Quasi Periodic Oscillations (QPOs) in high time resolution data.
