E. Bond, Space Telescope Science Institute, writes in CBET 1592 that a spectrogram (range 365-545 nm; resolution 0.43 nm) of this nova candidate was obtained with the SMARTS 1.5-m telescope on Cerro Tololo by M. Hernandez and F. Walter on 2008 Nov. 30.37 UT. The spectrum confirms that the object is a classical nova, of the "Fe II" type. The spectrum is dominated by broad emission lines of the Balmer series and of Fe II emission features. The FWZI of H-beta is about 4000 km/s. Continued spectroscopic and photometric observations are urged. Further visual magnitudes: Nov. 29.120 UT, 8.3 (A. Amorim, Florianopolis, Brazil); 30.775, 8.4 (N. J. Brown, Ellenbrook, West Australia). SUPERNOVA 2008hl IN NCG 7451 Discovery by LOSS of a possible supernova (CBET 1579): SN 2008 UT R.A. (2000.0) Decl. Mag.

IAUC 7995, 7996, 8001) also appeared in NGC 922. LV VELORUM H. E. Bond also reports on CBET 1597 that LV Vel -- the hydrogen-deficient central star of the planetary nebula "Longmore 4"; RA 10h 05m 45.7s DEC -44 21' 32" (2000), whose low-amplitude pulsations were discovered by Bonds and Meakes (1990, A.J. 100, 783) -- normally has a PG-1159-type absorption spectrum, with the O VI 381.1-383.4-nm doublet in emission. On three past occasions (one in 1992, two in 2006; Bond 2008, ASP Conf. Series 391, 129), the spectrum has changed temporarily to an emission-line [WCE] type, with strong emission at the C IV + He II complex near 465.9-468.6 nm and of O VI 529.1-nm. A spectrum obtained on 2008 Nov. 30.27 UT with the SMARTS 1.5-m telescope at Cerro Tololo by M. Hernandez and F. Walter shows that a new emission-line outburst is underway. Spectroscopic and photometric monitoring, including high-speed photometry of the star's GW Vir-type pulsations, is desirable throughout the duration of the current event. Guy M Hurst
