S. Nakano, Sumoto, Japan, reports the discovery of a possible nova (mag 8.4) on two 30-s unfiltered CCD survey frames taken on Apr. 18.784 UT by K. Nishiyama (Kurume, Fukuoka-ken, Japan) and F. Kabashima (Miyaki-cho, Saga-ken, Japan) using a 105-mm f/5.6 camera lens (limiting mag about 12.6). An unfiltered CCD image taken with a 0.40-m f/9.8 reflector on Apr. 18.809 yields mag 8.4 and the following precise position for the new object: R.A. = 18h05m58s.88, Decl. = -27o13'56".0 (equinox 2000.0). Nothing is visible at this position on their past survey frames taken on Apr. 13.765 (limiting mag 12.2) and 14.805 (limiting mag 12.8) using the 105-mm f/5.6 patrol camera or on the Digitized Sky Survey (DSS). A nearby USNO-B1.0 star has I mag 18.3 and position end figures 58s.38, 55".9.
