Abstract (from CDS):

S. Nakano, Sumoto, Japan, reports the discovery by K. Nishiyama (Kurume, Fukuoka-ken) and F. Kabashima (Miyaki-cho, Saga-ken) of a bright star (mag 9.5) on unfiltered CCD images obtained on Sept. 2.4594 UT with a 0.40-m f/9.8 reflector, brightening to mag 9.0 on Sept. 3.5119, the variable being located at R.A. = 17h57m32s.94, Decl. = -30o43'10".0 (equinox 2000.0). Nothing is visible at this position on their unfiltered CCD frames taken on Aug. 20.476 (limiting mag 12.8) and 21.470 (limiting magnitude 12.1) using a patrol camera (+ 105-mm-f.l. f/5.6 lens). They note nearby USNO-B1.0-catalogue stars at position end figures 33s.221, 10".56 (red mag 12.7) and 33s.015, 10".39 (red mag 14.8). Nakano also reports the independent discovery of this variable by Yukio Sakurai (Mito, Ibaraki-ken) at mag 9.7 on two survey frames taken on Sept. 3.437 and 3.438 using a Fuji FinePix S2 Digital Camera (+ Nikon 180-mm-f.l. f/2.8 lens), providing position end figures 33s, 09"; Sakurai adds that nothing is visible at this position on a frame taken on July 30 (limiting magnitude 12).
