NOVA AQUILAE 2010
Koichi Nishiyama and Fujio Kabashima, Japan, report on IAUC 9167 their 
discovery of a possible magnitude 12.4 nova on two 40-s unfiltered CCD 
frames (limiting magnitude 13.9) taken around 2010 Sept. 11.485 UT using 
a 105-mm f/4 camera lens + CCD.  Five 5-s unfiltered CCD images taken on 
Sept. 11.505 with Meade 200R 0.40-m f/9.8 reflector (+ SBIG STL1001E 
camera) yield the following precise position for the new variable:
RA 18h 47m 38.38s DEC -3 47' 14.1" (2000). Nothing is visible at this 
location on frames of Sept. 9.528 (limiting mag 13.9) and 10.466 
(limiting mag 14.0) or on the Digitised Sky Survey (1987 July 31; 
limiting red mag 18.3).

Hiroyuki Maehara, Kyoto University, reports on follow-up multi-colour 
photometry of this object with a 0.25-m telescope at the Kwasan 
Observatory around Sept. 11.59 UT yield position end figures 38s.38, 
13".9 and the following mags: Sept. 11.588, I_c = 10.45; 11.589, R_c = 
13.43; 11.590, V = 16.0.

Akira Arai and Mizuki Isogai obtained a low-resolution spectrum of Sept. 
11.597 with the 1.3-m Araki telescope showing H_alpha and O I 777.4-nm 
emission lines; the FWHM of the H_alpha emission is 1500 km/s.  These 
features suggest that this object is a classical nova.
