Re: CG CMa astrometry Remembering that I once took a CCD image to calibrate the VSNET chart of CG CMa (dated 1997 Dec. 27), I obtained the following astrometry of the "quiescent" (and is what I thought as that time) counterpart of CG CMa. The result is 07h 04m 05s.01 (J2000.0) -23o 45' 34".8 which agrees with the USNO coordinate within 1 arcsec. It seems that the presently outbursting star is different from this object (offset now unexplainable by proper motion from the POSS epoch). I suspect the true CG CMa is an unseen companion (on the POSS) to the previously suggested quiescent counterpart. Regards, Taichi Kato
