Dear All, After the spectroscopy by M. Fujii, HadV46 has turned out to be a nova. Congratulations, Haseda-san! Followup observations are strongly encouraged for this peculiar object. I would like to make a brief summary of this object up to now. Katsumi Haseda, Toyohashi, Aichi, Japan, has discovered an apparent variable (m_pg 10.6) on Mar. 5.81 UT 10-cm F4.0 twin patrol cameras. It is confirmed by photograph taken by the discoverer on Mar. 13.819 at m_pg 11.6, and by unfiltered CCD images taken by M. Uemura and T. Kato on Mar. 14.9 (mag 11.24), which indicates that it would not be a red variable and is in the rapidly declining phase. H. Yamaoka derived the position using this CCD image as 18h34m03s.16, -14o45'11".46 (equinox 2000.0). On the DSS1 or 2 images, there is no star brighter than mag 19, and the most neighbouring star is USNO0750.13593837 (rmag = 15.7, bmag = 17.1) about 3" west from the object. K. Takamizawa has provided the prediscovery magnitude estimates from his patrol films (see below), which and Haseda's prediscovery magnitudes show that it has been active since early February and experienced additional eruptive brightening in early March. Mitsugu Fujii, Kurashiki, Okayama, Japan, has taken a spectra of this object on Mar. 16.81 with 0.28-m reflector, which shows a strong H-alpha emission (FWHM = 940 km/s, steeper in blueward) then confirms that it is indeed a nova. Emission lines of H-beta and Fe II are also detected with blueward steepness or weak absorption. The spectrum can be seen at http://vsnet1.harenet.ne.jp/~aikow/hadv46.gif. S. Kiyota, Tsukuba, Japan, also taken a spectrum which shows H-alpha emission. The information including the sequence of reference stars are can be seen at http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Novae/hadv46.html.
