The source is found to be variable, both in flux and spectral shape, on time scales as short as a few ks. The spectrum clearly softens when the source brightens. A simple timing analysis suggests the presence of a variable soft excess that correlates with the primary continuum.","authors_text":"A. De Rosa, B. De Marco, F. Ursini, G. Matt, G. Ponti, J.
