V1721 AQUILAE = NOVA AQUILAE 2008 = POSSIBLE NOVA IN AQUILA The object reported on TA E-Circular 2488 has now been designated as V1721 Aquilae according to E. Kazarovets. D. D. Balam, University of Victoria, reports that a spectrogram obtained on Sept. 23.16 using the 1.82-m Plaskett Telescope, exhibits a strongly increasing continuum from 600 to 703 nm with a broad and flat-topped emission (HWZI about 2700 km/s, 6.5 nm) at the position of H_alpha. QY MUSCAE Bill Liller, Chile, reports on IAUC 8990 and direct to us his discovery of an apparent nova of magnitude 8.6 on a pair of Technical Pan photographs taken on 2008 Sept. 28.998 UT with a 85-mm camera lens (+ orange filter). The new object is located at: RA 13h 16m 30s DEC -67 37.0' (2000); 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, Australian Capital Territory, reports that his unfiltered CCD images yield the following position (estimated uncertainty +/- 4") for the apparent nova: RA 13h 16m 36.22s DEC -67 36'50.7"; 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. Brian 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 E. Kazarovets reports that the GCVS team assigns the designation QY Mus to this object.
