Pojmanski, Warsaw University Astronomical Observatory, reports the discovery of a possible nova on CCD images obtained with a 180-mm-focal-length (65-mm-aperture) telephoto lens in the course of the ASAS (cf. IAUC 8402, 8495). Pojmanski gives the new object's position as R.A. = 17h44m22s, Decl. = -34o16'.5 (equinox 2000.0 presumed), which is noted as being in an area crowded with nearby stars; V magnitudes for the new object: July 23.287 UT, [14; 25.284, 9.11; 26.296, 8.98; 26.311, 8.98. S. Nakano, Sumoto, Japan, reports the independent discovery of this new object at mag 8.7 by Hideo Nishimura (Kakegawa, Shizuoka-ken, Japan) on two 30-s Kodak T-Max films taken on July 26.565 with a Pentax 6x7 camera (+ 200-mm f/4.0 lens), with position end figures given as 22s, 15'59" (equinox 2000.0); nothing was visible at this location on Nishimura's survey films taken on July 20 (limiting mag 11). Nakano also forwards the following precise position from four unfiltered 20-s CCD frames taken by N. Hashimoto and T. Urata, Bisei Spaceguard Center, around July 26.596 using the 0.50-m f/2.0 reflector: R.A. = 17h44m21s.59, Decl. = -34o16'35".7 (magnitude 8.6). Nothing is visible at this location on Digitized Sky Survey images (limiting mag 17); the nearest USNO-A2.0 star (red mag 17.4) has position end figures 21s.987, 35".85.
