Three spectra obtained during the bright state in 1998 covering the range of typical variations in the Ca ii K line (left) and one corresponding spectrum in 2014 (right). We note that in 2014 the profile is of a P Cyg-type indicating an increased wind feature centred at 130 km s-1. Here, and in the following figures the wavelength scale is heliocentric and velocities are in km s-1 with respect to the star.
