Abstract (from CDS):
W. Liller, Vina del Mar, Chile, reports his discovery of an apparent nova (mag approximately 8.6) on a pair of Technical Pan photographs taken on Sept. 28.998 UT with a 85-mm camera lens (+ orange filter). The new object is located at R.A. = 13h16m30s, Decl. = -67o37'.0 (equinox 2000.0); additional magnitudes from Liller: Sept. 15.023, [11.5; Oct. 4.032, 8.9. Liller adds that a weak spectrogram taken on Oct. 4.015 with a Schmidt camera of focal length 300 mm (+ orange filter + Technical Pan film + 100-mm x 100- mm transmission grating with 75 grooves/mm) shows a single broad emission line at the expected position of H_alpha (width at least approximately 230 nm). V. Tabur, Wanniassa, Australian Capital Territory, reports that his unfiltered CCD images, taken with an intentionally significantly defocused Nikon ED 77-mm-aperture f/2.8 camera lens (+ SBIG ST8XE CCD camera) yields the following position (estimated uncertainty ± 4") for the apparent nova: R.A. = 13h16m36s.22, Decl. = -67o36'50".7; while the variable is involved with a nearby star due to the defocused images, he provides the following magnitudes for the apparent nova: Sept. 19.418, [11.6; 21.378, 9.9; 23.401, 9.8; 24.378, 9.7; 25.378, 9.2; 27.389, 8.7; 28.383, 8.6; 29.436, 8.5 (cloud interfering); 30.397, 8.1; Oct. 1.395, 8.3. P. Williams, Heathcote, N.S.W., reports visual mag 8.9 on Oct. 2.440. M. Templeton, AAVSO, forwards the following position end figures and magnitudes from P. Nelson, Ellinbank, Victoria, Australia: 36s.44, 47".8; B = 10.26, V = 9.31, at Oct. 2.44. B. A. Skiff, Lowell Observatory, reports that a USNO-B1.0- catalogue star of blue mag 19.9 and red mag 17.5 has position end figures 36s.47, 47".9, noting that a star is also present with 0".5 of Nelson's position on a plate taken via the U.K. Schmidt Telescope H_alpha survey. E. Kazarovets reports that the GCVS team assigns the designation QY Mus to this object.
