The broad Halpha and Hbeta lines show evidence for two components to their profiles with distinctively different spatial and kinematical properties. Also, blue-shifted Balmer absorption lines are seen which could correspond to the accretion disk photosphere or a slow out-flow. A broad component seen bluewards from the Hbeta line very likely corresponds to HeII4686. The HeII line appears very broad and shows distinctively different characteristics from those shown by the Balmer lines, impying that High Ionization lines are produced in a different region than that producing the Balmer lines. These exciting results are combined to draw a picture of the properties of the BELR in this Seyfert galaxy.
