The Central Bureau for Astronomical Telegrams (Central Bureau Electronic Telegram 29, preliminary announcement from forthcoming IAU Circular) informed us that Akira Takao, Kitakyushu, Japan, discovered a nova in Ophiuchus on unfiltered CCD images taken July 10.598 and July 16.523 UT at magnitudes 11.4 and 11.2, respectively, using a 120-mm f/4 telephoto lens.
This nova is past maximum and has appeared in images taken by various observers since at least March 21, 2003.

2003 July 31: A lucky first spectrum of this nova [below] very low on southern horizon after dusk through cloud breaks with the telescope pointing almost horizontally! An offset from nearby bright Antares to the nova field with only two images from many faintly showing the nova near the bottom edge of the frame and identified by the bright telltale peak of H-alpha in the spectrum [using Altair's spectrum for reference]. The nova starfield as imaged subsequently confirmed via the AAVSO chart shown.
2003 Aug 9: Cloudless conditions but haze in late twilight [and temps in 90'sF!] for co-added 5 m exposure and better SN ratio.
2003 Aug 14: Clear and cooler for longer single exposure - nova running into twilight for my southern gap.
2003 Aug 22: Clear but some horizon hazy - 5m slightly trailed image still reveals Ha and other emission lines.
