[Patrick Schmeer]

2015 02 12.8784 UT
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.
