Graham and W. Li report the LOTOSS discovery of an apparent supernova. Unfiltered KAIT images taken on June 24.5 and 25.5 UT showed the supernova at magnitude about 14.5 and about 14.6, respectively. SN 2003gf is located 19.2" east and 3.9" south of the diffuse nucleus of MCG -04-52-26 at: R.A. = 22h 13m 40.94s Decl. = -21o 44' 03.3" (equinox 2000.0). Photometry for a chart is currently being investigated; charts will be posted and announced when they are ready. Please report your observations of 2208-22 SN 2003GF to the AAVSO, making sure to indicate what chart and comparison stars were used. ---------------------------------------------------------------------------- 0833-47 BB VELORUM The dwarf nova type cataclysmic variable BB VEL may be in outburst, as indicated by the following observation: AAVSO Observer UT Mag.
