Abstract (from CDS):
N. N. Samus, Institute of Astronomy, Russian Academy of Sciences, informs the Central Bureau that the GCVS designation V598 Pup has been assigned to the apparent nova initially posted by Read et al. (
http://www.astronomerstelegram.org/?read=1282) as a bright x-ray transient (as seen with the XMM-Newton satellite on Oct. 8 at 0.2-2 keV) that is located at R.A. = 7h05m42s.7, Decl. = -38o14'42" (equinox 2000.0), and subsequently found as a bright star optically (within the reported 8" x-ray error circle) by Torres et al. (ibid.,/?read=1285), who explain that their spectroscopy obtained on Nov. 16.34 UT reveal numerous features suggestive of a nova in the auroral phase. E. O. Waagen, AAVSO, writes that S. Dvorak (Clermont, FL, U.S.A.) reports V = 10.28 and B = 11.25 for V598 Pup from CCD images obtained on Nov. 18.38; A. Henden, AAVSO, has measured the following position end figures from Dvorak's V image: 42".51 (± 0".05), 39".3 (± 0".1). Other CCD magnitudes forwarded by the AAVSO for the apparent nova: Nov. 19.27-19.37, 11.6 (A. Oksanen, San Pedro de Atacama, Chile, unfiltered); 19.506, V = 10.17 (W. Dillon, Missouri City, TX, U.S.A.). Visual magnitude estimate by A. Amorim, Florianopolis, Brazil: Nov. 20.036, 9.9.
