Scientific paper

One hundred and sixty one Exosat observations of 30 emission line Active Galactic Nuclei (AGN's) in the Piccinotti sample were studied for variability. For each source long (from days to months) and short (from minutes to hours) term luminosity variations were searched for using soft (LE: 0.05 to 2 keV) and long (ME: 1 to 8 keV) light curves. Spectral variability was also investigated for all the 14 objects that showed long time variations in both the energy bands.
