Cbet circular No. 1994, issued on 2009 Oct. 26, announces the discovery by K. Nishiyama and F. Kabashima of an apparent new Nova (mag 9.3) on images taken with a 105-mm f/4 camera lens in the course of their nova survey. Nothing is visible on their two recent survey frames taken on 20 & 21 October 2009 (limiting magnitude 13.9).

On our images taken on October 27.09 through a 0.25-m, f/3.4 reflector + CCD, near Mayhill (NM), we can confirm the presence of an optical counterpart with unfiltered CCD magnitude about 9.0 (USNO-B1 Catalogue reference stars) at coordinates:

R.A. = 18 31 32.81, Decl.= -16 19 07.5
(equinox 2000.0; USNO-B1 catalogue reference stars).
