**************************************************************** Possible Nova in Cygnus: Now Confirmed to be a Nova = Nova Cyg 2001 **************************************************************** Dr. Iijima has reported the following spectroscpy of the possible nova in Cygnus. The object is indeed a classical nova! Congratulations, Nakamura-san! The VSNET page on this nova: http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/Novae/ncyg01.html Date: Wed, 18 Jul 2001 05:47:25 +0200 (MET DST) From: Takashi Iijima <iijima@astras.pd.astro.it> Subject: Nova Cyg 2001 July 18 2001, Asiago, Italy Optical spectra in the range from 430 to 680 nm of the possible nova in Cygnus reported by Y. Nakamura were taken at July 17.9 UT using a Boller and Chivens spectrograph mounted on the 122 cm telescope of Asiago Astrophysical Observatory of the University of Padova. The spectra show broad emission lines of H I, Fe II, and probably Na I D and N II. Some prominents emission lines are accompanied by P Cygni type absorption components. The FWHM of H-alpha emission component is about 950 km/s and a weak absorption component blue-shifted by about -1200 km/s is seen. This object could be a classical nova in the early decline stage from light maximum. T. Iijima Astronomical Observatory of Padova, Asiago Station, I-36012 Asiago (Vi) ITALY --- We have been undertaking on photometric campaigns on several super- outbursting dwarf novae and peculiar variable stars. News and call for observations on these objects will be issued on our regular weekly "News from VSNET" bulletins. Those who immediately need information should make an access to the VSNET website, and click on VSNET campaign list. ---------------------------------------------------------------------------- VSNET (Variable Star Network) is an international variable star observing network, covering various areas of novae, supernovae, cataclysmic variables (CVs), X-ray transients, and other classical eruptive, pulsating, and eclipsing variables. VSNET is one of invited contributing organizations to the SkyPub AstroAlert system. VSNET Home Page: http://vsnet.kusastro.kyoto-u.ac.jp/vsnet/ CCD observations of such targets are a relatively easy task for a 20-40cm telescope; simply take as many CCD frames (with exposure times 10-30 sec) as possible, spanning several hours per night. The only requirements are the weather and your patience! If you need more help on the observing technique, please feel free to ask on the vsnet-campaign list. We would sincerely appreciate volunteers who would join the VSNET Collaboration team to study the wonders of these exotic variable stars. To join the VSNET campaign collaborative list, send an e-mail to vsnet-adm@kusastro.kyoto-u.ac.jp (VSNET administrator) with a line "SUBSCRIBE vsnet-campaign." or your comment to join the collaboration team. ----------------------------------------------------------------------------
