Following the posting on the Central Bureau's unconfirmed-objects webpage about another possible nova in Ophiucus, today we performed some follow-up of this object remotely through a 0.25-m, f/3.4 reflector + CCD, near Mayhill (NM).
We can confirm the presence of a relatively bright counterpart at coordinates:
R.A. = 17h33m29s.62, Decl. = -27o 01'14".5 (equinox 2000.0; UCAC-2 catalogue reference stars).
Our multicolor photometry provides the following values: 2008, Jun. 2.23, B= +13.9, V= +12.8, R= +11.4 (accuracy +/- 0.1 magnitudes in each color).
Comparison with a UK Schmidt Telescope red plate, obtained on 1991, August 11 show nothing in this position (limiting magnitude near 20). See below our confirmation image (details are on the caption; click on it for a bigger version).
