Koichi Nishiyama, Kurume,Japan and Fujio Kabashima, Miyaki, Japan report a
discovery of possible nova (mag.= 10.9) in Sgr on two 40-s unfiltered CCD
frames taken around
2015 Feb. 12.87837UT ( limiting magnitude=13.3 ), 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 2015
Feb 12.891UT ( limiting magnitude=16.6 ), 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 one past survey frames taken on 2015 Feb 02.887 UT(limiting
mag.= 12.5) nor on DSS, USNO-B1.0, We have checked in Minor Planets. nearest
star in USNO B1.0 has position end figures 24s979, 35"69, distance 2"6,
magnitudes B2=15.40 R2=14.39 I=14.66

2015 02 12.840 UT
Mag.= 11.2, position end figures 25s.24, 32".6 discovered independently by
H. Nishimura, Shizuoka-ken, Japan, using 200-mm f/3.2 lens + a digital
camera.
