The IAU CBAT TOCP page identifies the object as PNV J18202726-2744263 [V5592 Sgr] and gives the earliest report (Koichi Nishiyama and Fujio Kabashima) date and time of 2012 July 07.4986 UT and their magnitude 7.8 unfiltered CCD.

Coordinates: 18 20 27.26 -27 44 26.3  (2000.0)

Alert Notice 463: Nova Sagittarii 2012 No. 3 = PNV J17522579-2126215 [V5591 Sgr]

July 3, 2012:

Event: Nova Sagittarii 2012 No. 3 = PNV J17522579-2126215  [V5591 Sgr]

Discovered independently by:
 - Koichi Itagaki (Yamagata, Japan, reported by Hitoshi Yamaoka, Kyushu University)
 - Yukio Sakurai (Mito, Ibaraki-ken, Japan)

Discovery Magnitude:
 - Itagaki: magnitude 10.3 on an unfiltered CCD image taken with a 0.21-m reflector
 - Sakurai: magnitude 9.9 on four 20-s frames taken with a Fuji FinePix S2 Digital Camera + Nikon 180-mm f/2.8 lens

Special Notice #273: Possible Nova in Ophiuchus = PNV J17260708-2551454 [V2676 Oph]

March 28, 2012:  A possible nova in Ophiuchus [V2676 Oph] was announced on the IAU CBAT Transient Objects Confirmation Page (TOCP) page with the name PNV J17260708-2551454. It was discovered by H. Nishimura (Shizuoka-ken, Japan) at unfiltered magnitude 12.1 on 2012 March 25.789 UT on three frames using Canon 200-mm f/3.2 lens + Canon EOS 5D Digital Camera. Spectra suggest that the object is an Fe II-type classical nova.
