Itagaki, Japan, reports on IAUC CBET 1512 the discovery of a variable star on his CCD survey image taken on 2008 Sept.22.5 UT with a 0.21-m reflector; a confirming unfiltered CCD image taken on Sept. 22.586 with a 0.60-m reflector yields mag about 14.0 and the following precise position: RA 19h 06m 28.58s DEC +07o06'44.3" (2000). Nothing brighter than mag 17.0 is visible at this position on Itagaki's patrol image taken on 2007 Nov. 2.396. The 2MASS catalogue contains a very faint star (J = 16.6, H = 15.5, K_s = 14.7) with position end figures 28s.60,44".5. Following an appeal from the Central Bureau, V. Nevski, Belarus, (0.30-m reflector) reports that an unfiltered CCD image obtained on Sept. 22.8 yields red mag 14.0 and position end figures 28s.59, 44".6 for the variable, adding that nothing is visible at this position on Digitised Sky Survey images from 1951 July 5 and 1987 July 30 (limiting mag approximately 20). E. Y. Hsiao et. al., Department of Physics and Astronomy, University of Victoria, write that an optical spectrum was obtained on Sept. 23.16 UT using the 1.82-m Plaskett Telescope as part of its targets-of-opportunity spectroscopy program. The transient exhibits a strongly increasing continuum from 600 to 703 nm with a broad and flat-topped emission (HWZI about 2700 km/s, 6.5 nm) at the position of H_alpha, which suggests that this could be a heavily reddened classical (He/N) nova. (136108) HAUMEA The IAU's Committee on Small Body Nomenclature and Working Group for Planetary System Nomenclature have agreed to give to the transneptunian dwarf planet, or 'plutoid', (136108) 2003 EL_61 (cf. IAUC 8577) the name "Haumea", with the citation given on MPC 63878. At the same time, the IAU is giving the name Hi'iaka to (136108) Haumea I -- the larger, outer satellite (cf. IAUC 8577) -- and the name "Namaka" to (136108) Haumea II -- the smaller, inner satellite (cf. IAUC 8636).
