Scientific paper

The VLA FIRST radio survey recently discovered a new, extremely bright quasar that is the second brightest optical object in the sky at z>0.1. Optically classified as a Narrow-line Seyfert 1 galaxy (NLS1), PHL 1811 is not typical of this class of objects because it is a very weak X-ray source. We propose short exploratory UV spectroscopic observations of this new bright quasar that will reveal its true nature and permit us to identify potential applications of future deeper observations. PHL~1811 may be the brightest luminous NLS1, in which case the study of the profiles and ratios of the emission lines will be valuable. Alternatively, PHL 1811 may be the brightest BALQSO, and the structure and composition of the BAL flow may be studied. (abridged)
