The spectral type changed from nearly Seyfert 2 type (1.95) to Seyfert 1.5 type in comparison to previous observations taken ten to twenty years before. In a subsequent variability campaign we wanted to investigate whether this outburst was a single event or whether the variability pattern following the outburst was similar to those seen in other variable Seyfert galaxies. In addition to a SALT spectral variability campaign, we carried out optical continuum as well as X-ray ","authors_text":"D. Chelouche, D. Grupe, M. Haas, M. Ramolla, M. W. Ochmann, M. Zetzl, N.
