Tabur of Wanniassa, Australian Capital Territory. The 9.7 red magnitude object appeared on unfiltered CCD images taken by Tabur on October 25.44 and 25.48 UT. Tabur reports that the object is located at the following position: R.A. = 17h 47m 21s.74 Decl. = -23o 28' 23".1 (2000) Please report this object to the AAVSO as: 1741-23 N SGR 02#4 An AAVSO chart prepared by Aaron Price and Mike Simonsen shows the location of the possible nova and has been posted on the AAVSO web page. This chart is accessible via the following url: http://charts.aavso.org Congratulations to V. Tabur on this discovery! ---------------------------------------------------------------------------- 0106+34 FN ANDROMEDAE The dwarf nova type cataclysmic variable FN AND is in outburst, as indicated by the following observations: AAVSO Observer AAVSO Observer UT Mag.
