S. Nakano, Sumoto, Japan; and H. Yamaoka, Kyushu University, report the discovery by Koichi Itagaki (Teppo-cho, Yamagata, Japan) of a possible nova (mag 10.0) on his unfiltered CCD survey frames taken on Aug. 16.515 UT using a 0.21-m f/3 reflector (limiting magnitude 15), the position given as R.A. = 17:38:19.68, Decl. = -26:44:14.0 (equinox 2000.0). Confirming images (limiting mag 18.5) taken by Itagaki with a 0.60-m f/5.7 reflector on Aug. 16.526 yield mag 10.1 and position end figures 19s.70, 14".0. Nothing is visible at this position on Itagaki's frame taken with the 0.21-m reflector on 2008 June 10.645 (limiting mag 15.0) or on the Digitized Sky Survey (DSS). K. Kadota (Ageo, Japan) also confirmed the new star on an unfiltered CCD frame taken on Aug. 16.576 using a 0.25-m f/5 reflector, measuring mag 10.2 and position end figures 19s.70, 13".8 (GSC-ACT catalogue reference stars for the astrometry). Kadota adds that the nearest USNO-B1.0-catalogue stars have position end figures 19s.81, 15".4 (red mag 16), and 19s.88, 13".4 (red mag 17-18), noting that nothing is visible at the position of the new star on red DSS images from 1991 and 1996. Yamaoka writes that there is no object brighter than mag about 14.0 on a ASAS-3 V-band image (cf. Pojmanski 2002, Acta. Astron. 52, 397) taken on 2009 Aug. 14.142. Itagaki further reports that the new star has faded to mag about 11.1 on Aug. 17.428.
