Although a bright(ish) new nova has been discovered in Scorpio it is well to
the south and sadly not visible from the UK. However, for those of you with
access to telescopes in the southern hemisphere you are encouraged to have a
go at it.
It was discovered by Hideo Nishimura, Shizuoka-ken of Japan on 2016 June
10.63UT at magnitude 12.4 using a 200-m
f/3.2 lens + Canon digital camera EOS 5D and CCD. It is located at: RA 17h
38m 19.27s DEC -37 25' 07.7" (2000).
Apparently, nothing was visible at this location on an image of 2016 May
14.71UT, May 18.61UT or June 5.53UT to a limiting magnitude of 13.0.
A mag 11.8, pre-discovery image has been found by T. Kojima, Gunma-ken,
Japan, on three frames using 135-mm lens + Canon EOS 6D digital camera, who
also advise nothing was visible at this location on two patrol frames
(Limiting mag.= 13) taken on 2016 June 5.582 UT.
K. Ayani, Bisei Astronomical Observatory (BAO) obtained a low-dispersion
spectrogram (resolution 0.5 nm, range 400-800 nm) of this PNV with the BAO
1.01-m telescope. It has a prominent and broad H-alpha emission line (FWHM
about 1800 km/s, equivalent width about 23 nm) and a broad H-beta emission
line, which shows that the PNV is a nova in early phase.
As always, you should report your observations to the BAAVSS and if you are
unsure how to do that then please contact the Director.
