Possible Nova in Sco

Following the posting on the Central Bureau's unconfirmed-objects webpage about a possible nova in Sco, on 2008 Sep. 3.45 we performedsome follow-up of this object remotely, from Moorook (Australia),through a 0.1-m, f/5 refractor + CCD.

We can confirm the presence of a relatively bright object (unfilteredmagnitude about 9.6) at coordinates:

R.A. = 17h57m32s.93, Decl. =-30o43'10".3 (equinox 2000.0; UCAC-2 catalogue reference stars).

Comparison with an archive UK-Schmidt Red plate (obtained on 1992,June 03) show no counterparts at this precise coordinates; a nearbyfield star, with position end figures: 32s.95, 08".1, has magnitudeabout 18.
