V335 Vulpeculae
Abstract
U. Munari, T. Tomov, and D. Moro, Padova and Asiago Astronomical Observatories; and A. Henden, U.S. Naval Observatory, Flagstaff, write: "The carbon symbiotic star V335 Vul seems to be undergoing a bright outburst. Photometry with the USNO 1.0-m in Flagstaff: June 23.32 UT, V = 12.87, B-V = +5.01; Dec. 3.05, V = 11.31, B-V = +3.06. Echelle and Boller & Chivens spectroscopy obtained with the Asiago 1.22- and 1.82-m telescopes indicate a tenfold increase in the intensity of the emission lines, compared to quiescent conditions (cf. IBVS 4668). The strongest emission lines include H-alpha, H-beta, Na I D, and the near-infrared Ca II triplet."
