2014 03 31.8202
Koichi Nishiyama, Kurume, Japan and Fujio Kabashima, Miyaki, Japan
report a discovery of possible nova (mag.= 10.9) in Cyg on two 40-s
unfiltered CCD frames taken around 2014 Mar. 31.78990 UT (limiting
magnitude=13.1), using a 105-mm f/4 camera lens (+SBIG STL6303E
camera). We have confirmed immediately the appearance of our
discovery this PN on five 5-s unfiltered CCD frames taken around
2014 Mar. 31.8202 UT (limiting magnitude=17.6), 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 past survey frames taken on
2014 Mar. 27.781 UT (limiting mag.= 13.4) but we found same object
12.4 mag. Mar. 30.769 UT (limiting mag.= 13.5) nor on DSS, USNO-B1.0,
We have checked in Minor Planets. nearest star in USNO B1.0 has
position end figures 42s769, 33"99, distance 7"0, magnitudes
B2=17.94 R2=15.41 I=14.56

(I corrected some obvious typos)
