Liller estimated the nova to be photovisual magnitude 11.2. The nova was visually confirmed by Rod Stubbings, Australia. Liller has measured the position of the nova as: R.A.=05h 25m 01.60s Decl.=-70 degrees 14' 17.3" (equinox 2000.0) For more information on this discovery, an image of the new nova, and an AAVSO 'e' scale Preliminary chart please see AAVSO Alert Notice 277. This Alert Notice will be posted on the AAVSO web page (www.aavso.org) shortly. Congratulations to Bill on his latest discovery! ---------------------------------------------------------------------------- 0207-63 WX HYDRI The dwarf nova type (SU UMA subclass) cataclysmic variable WX HYI appears to be in outburst, as indicated by the following observations: AAVSO Observer AAVSO Observer UT Mag.
