Chassagne of Ile de Reunion. The 14.1 magnitude object appears on an unfiltered CCD frame taken on OCT 7.90 UT. The following position has been reported: R.A. = 22h 54m 21s.49 Decl. = -45o 20' 26".9 (2000) which is 4".0 east and 22".6 north of the center of NGC 7400. Please report the object to the AAVSO as: 2248-45 SN 2002GE An AAVSO 'f' scale chart prepared by Aaron Price and showing the location of SN 2002GE will be posted shortly on the AAVSO web page. Ths chart will be accessible via the following url: http://charts.aavso.org Congratulations to R. Chassagne on this discovery! ---------------------------------------------------------------------------- 0043+56B GX CASSIOPEIAE The dwarf nova type (SU UMA subclass) cataclysmic variable GX CAS appears to be in outburst, as indicated by the following observations: AAVSO Observer AAVSO Observer UT Mag.
