Hsiao, Lawrence Berkeley Laboratory; and D. W. E. Green, Harvard University, report that a spectrogram (range 382-714 nm, resolution 0.3 nm) of PNV J21095047+1348396, obtained on May 29.42 UT with the 1.82-m Plaskett Telescope of the NRCC, shows a steep blue continuum with broad asymmetric Balmer absorption lines. H-alpha exhibits a broad absorption profile with a sharp (1.2-nm FWHM) central emission spike.
