Abstract (from CDS):

G. Pojmanski, D. Szczygiel, and B. Pilecki, Warsaw University Astronomical Observatory, report a new apparent outburst of a variable that was first discovered by the "All Sky Automated Survey" (ASAS) on 2003 July 23 and is located at R.A. = 15:09:46, Decl. = -21o47'.7 (equinox 2000.0). Three-minute CCD exposures taken with the ASAS3V instrument (70-mm-diameter, 200-mm f.l. f/2.8 telephoto lens + Johnson V filter; pixel size 14".8, rms astrometric accuracy 4") yield the following V magnitudes: 2003 July 14.058 UT, 11.50; 15.155, 11.49; 23.071, 11.20; 25.189, 10.86; Aug. 2.034, 10.47; 7.069, 10.60; 11.040, 10.81; 21.049, 11.20; 25.003, 11.35; 27.005, 11.45; Sept. 3.992, 11.47; 2009 Mar. 28.255, 11.55; 28.272, 11.48; 31.249, 10.93; 31.262, 10.95; Apr. 5.369, 10.38. I-band exposures this month by Pojmanski with the 1.3-m OGLE telescope suggest that this variable (designated ASAS J150946-2147.7) is associated with the brighter of two close 2MASS sources: 2MASS J15094657-2147462 (J = 10.5, H = 10.4, K = 10.3).
