Nova Centauri 2012 = PNV J13410800-5815470.

Abstract (from CDS):

F. M. Walter, Stony Brook University, obtained a low-resolution (0.31-nm) red (560-690 nm) spectrogram of PNV J13410800-5815470 on Mar. 27.3 UT using the SMARTS 1.5-m telescope (+ RC spectrograph) at Cerro Tololo. The variable is a classical "Fe II"-type nova. Emission lines are seen from Fe II multiplet 74 at 614.9, 623.9, and 645.6 nm. The H-alpha line has an equivalent width of -19.0 nm, with a FWHM of 2.5 nm. There is a P-Cyg absorption feature at about -1600 km/s, and a notch in the blue wing of the emission line at about -800 km/s. There is broad emission with P-Cyg absorption in the vicinity of Na D lines. If the absorption is due to Na D in the ejecta, this suggests outflow velocities between -700 and -2300 km/s. The interstellar Na D lines are narrow, with equivalent widths of about 0.1 nm. Also, BVRIJHK photometry was obtained with the SMARTS 1.3-m telescope (+ Andicam dual channel photometer) at Cerro Tololo on Mar. 24.16, 26.14, and 27.11; the V magnitude decreased from 9.4 to 9.9 over this interval.
