Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki,Japan report
a discovery of possible nova (mag.= 12.6) in Aql on two 40-s unfiltered
CCD frames taken around 2012 Oct. 20.429 UT ( limiting magnitude=13.8 ),
using a 105-mm f/4 camera lens (+SBIG STL6303E camera). We have
confirmed immediately the appearance of our discovery this PN on five
3-s unfiltered CCD frames taken around 2012 Oct 20.435 UT ( limiting
magnitude=18.5 ), using a Meade 200R 0.40-m f/9.8 reflector (+SBIG
STL1001E camera). (lens magnitude of referred catalogue Hipparcos,
others reference catalogue GSC-ACT) Nothing is visible at this location
on two past survey frames taken on 2012 Oct 12.470 UT(limiting mag.=
14.1) and 14.472 UT (limiting mag.= 14.1) nor on 2MASS,USNO-B1.0, but
prediscover mag=13.2 Oct. 15.428 UT ( limiting magnitude = 14.1 ),.
mag=12.3 Oct. 18.434 UT ( limiting magnitude = 14.1 ),. mag=12.2 Oct.
19.434 UT ( limiting magnitude = 14.0 ).. We have checked in Minor
Planets. nearest star in USNO B1.0 has position end figures 34s913,
42"48, distance 0".7, magnitudes R1=19.25 I=18.09
