G. Sun, Wenzhou, Zhejiang, China; and X. Gao, Urumqi, Xinjiang, China, report the discovery of a possible nova (mag approximately 11.5) on several 60-s survey images (limiting mag about 13.5) taken by Gao in the course of their nova survey at Mt. Nanshan on Feb. 23.947-23.963 UT using a Canon EOS 350D camera (+ 135-mm f/2 lens). Their images taken on Apr. 28 by Sun with a 1-m f/8 reflector at Weihai yield the following position for the variable: R.A. = 17h45m05s.40, Decl. = -20o03'21".5 (equinox 2000.0). Nothing was visible at this location on images taken by the discoverers on 2008 Aug. 23, Sept. 4, 25, and Oct. 3 (limiting mag presumably also about 13.5); they report that nothing is visible at this position on Digitized Sky Survey images from 1950 June 19 (limiting red mag 20.0), 1980 Aug. 2 (limiting infrared mag 19.5), and 1991 Aug. 2 (limiting red mag 20.8). Additional available magnitudes from Sun and Gao for the variable: Feb. 27.960, 12.1; 28.968, 12.0; Mar. 2.963, 13.0; 3.964, 12.8; 6.968, 13.1; 22.949, 11.6; 26.950, 12.1; 27.947, 12.5; Apr. 28.837, 13.2.
