%X We discuss the optical coronal line spectra observed for a sample of 19 Narrow-Line Seyfert 1 galaxies. We find no correlation between the coronal line strength and the soft X-ray power-law index derived from ROSAT PSPC data. There is a trend for broader coronal lines to have larger equivalent widths. In addition, a strong trend is found between line width and velocity relative to the NLR. This trend is interpreted in terms of a decelerating outflow, originating close to the nucleus.
