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.
