Abstract (from CDS):

G. Pojmanski, Warsaw University Astronomical Observatory, reports the discovery on ASAS-3 200-mm-f.l.-lens telephoto images (cf. IAUC 8617) of an apparent nova located at R.A. = 17h33m13s, Decl. = -24o21'.1 (equinox 2000.0). Available ASAS V magnitudes: 2005 Oct. 26.013 UT, [14; 2006 Feb. 9.390, 12.08; 10.327, 12.04; 10.329, 11.94; 10.342, 12.07; 11.334, 11.48; 12.329, 11.07; 13.336, 11.47. The object is also clearly visible in the ASAS-3 I-band images taken on Feb. 8.379. H. Yamaoka, Kyushu University, provides his average of measurements of the position of the new nova from I_c-band CCD images taken by S. Kiyota on Feb. 12.83 and by H. Maehara on Feb. 10.83: R.A. = 17h33m13s.06, Decl. = -24o21'07".1 (rms about 0".2; UCAC2 reference stars); the nearest star in the USNO-B1.0 catalog is about 3" away from this position, and a red Digitized Sky Survey image from 1991 Aug. 11 does not show any object to limiting mag about 18 (affected by nearby stars). Yamaoka adds that low-resolution spectra of this new object – taken around Feb. 12.9 by K. Ayani with the Bisei Astronomical Observatory (BAO) 1.01-m telescope, by H. Naito and S. Narusawa (Nishi-Harima Astronomical Observatory) with the 2.0-m NAYUTA telescope, and by M. Fujii (Ibara, Okayama, Japan) with a 0.28-m telescope – show prominent Balmer lines with P-Cyg profiles superimposed on a very red continuum, which suggests that the object is a classical nova near maximum. Deep interstellar Na D absorption is also seen. From the BAO spectrum, the FWHM of H_alpha emission is 560 km/s, and an absorption minimum of that is blueshifted by 530 km/s from the emission peek. O I 777.3-nm and Fe II emissions are also detected with P-Cyg profiles.
