Abstract (from CDS):

W. Liller, Vina del Mar, Chile, writes that an objective- transmission-diffraction-grating CCD spectrum (75 grooves/mm; aperture 100x100 mm; 0.20-m Schmidt camera), obtained on Oct. 11.002 UT, shows an exceedingly strong and broad H_alpha emission line (FWHM at least 5100 km/s); the brightness of its flat maximum was approximately 7.7 times that of the surrounding continuum. A spectrogram obtained on Oct. 12.012 shows the H_alpha emission line basically unchanged, with its maximum brightness now estimated to be 6.2 times that of the surrounding continuum (FWHM = 5035 km/s). Photometry by Liller: Oct. 10.991, V = 10.27 ± 0.03, B-V = +0.39 ± 0.05; 12.001, V = 10.60 ± 0.03. L. A. G. Monard, Pretoria, S. Africa, reports that a CCD image taken on Oct. 11.704 yields mag 9.5 and the following precise position: R.A. = 15h17m52s.48, Decl. = -61o57'16".4 (equinox 2000.0).
