Abstract (from CDS):

Alfredo Jose Serra Pereira, Carnaxide, Portugal, reports his discovery of an apparent nova (mag 7.0) during his regular visual patrol on Nov. 14.23 UT with 14x100 binoculars, the position given as R.A. = 8h16m.2, Decl. = -34o15' (equinox 2000.0); he had nova- hunted for 625.85 hr since his discovery of the 2001 nova V4740 Sgr (cf. IAUC 7706). Pereira adds that nothing was detected at this position in his visual searches during Nov. 6.23, 7.22, 8.23, 10.23, and 11.22 down to mag about 8; additional monitoring during Nov. 14.243-14.256 also yielded mag 7.0. Following requests by the Central Bureau, CCD astrometry for the variable has been reported by J. E. McGaha (Tucson, AZ, U.S.A., 0.62-m f/5.1 reflector) and by J. Young and H. Rhoades (Table Mountain 0.61-m f/16 Cassegrain reflector). From his 1-s exposure on Nov. 14.411, McGaha measures R.A. = 8h16m18s.01, Decl. = -34o15'24".1, red mag 6.5 (USNO-A2.0 reference-star catalogue). From four exposures "in surprisingly good seeing for the low altitude" on Nov. 14.47-14.48, Young measures average position end figures 17s.99, 25".0, mag 6.7 in a red filter (USNO-B1.0 reference-star catalogue); Young also estimated visual mag 6.4 at this time. Young adds that comparison with a red image from the Digitized Sky Survey shows only an extremely faint star (mag about 20) at the same spot as the apparent nova (located in a fairly empty area surround by "a busy star field").
