Hola everyone -
The nova candidate reported to me by Brian Skiff had, according to my CCD measurements through clouds, a broadband V mag of 9.98 +/- 0.7 at Oct. 27.0149 U.T. My position for it is (2000) R.A. 17h 47m 21.629s +/- 0.047s and Dec. -23d 28' 21.44" +/- 0.39". Three Tycho stars were used for the photometry; these plus three GSC stars were used for the astrometry.
I'll try for a spectrum tonight; the weather might even be clear by then.
All the best to all, Bill/William
The field of the new possible nova in Sgr was observed by the OGLE II team (Udalski et al. 1997, Acta Astron. 47, 319). No variable star at this location has been reported (field: OGLE II BUL-SC14, Wozniak et al. 2002, Acta Astron. 52, 129). Together with the lack of a bright 2MASS counterpart, the object is most likely a nova (or an eruptive object).
