The spectra covered the range 3800-7000 angstroms. All the lines of the Balmer series up to H-8 appeared strongly in emission. The equivalent widths of the H-alpha and H-beta lines (the strongest emission features) on 28 September 2005 were -550+-25 angstrom and -220+-20 angstrom, respectively and the FWHM 1800+-30 km/s in both lines.</style></abstract></record></records></xml>
