Subject: [baavss-alert] PNV J17381927-3725077: new transient (12.4 mag) in Scorpius

PNV J17381927-3725077

Discoverer: Hideo Nishimura (Shizuoka-ken, Japan)

R.A. 17h38m19.27s Decl. -37°25'07.7" (J2000.0)
2016 June 10.629 UT, 12.4 mag (CCD, unfiltered)

"2016 06 10.629 UT
Discovered by H. Nishimura, Shizuoka-ken, Japan
using 200-mm f/3.2 lens + a Canon digital camera
EOS 5D, who writes nothing is visible at this location
on his recent frames taken on 2016 May 14.712,
May 18.602 and June 5.532 (Limiting mag = about
13.0) UT using same patrol camera."

Two USNO-B1.0 stars (both about 17 mag) are
within 1" of the transient's position.

Spectroscopy, precise astrometry, and time-
resloved photometry are required.

Clear skies,
Patrick

PNV J17381927-3725077 spectroscopically confirmed
(= "Nova Scorpii 2016")

http://www.cbat.eps.harvard.edu/unconf/ ... 25077.html

2016 06 11.65 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.

Here is my spectrum from 2 nights ago.
It isn't the brightest object at mag V=12.39

Follow up spectrum from last night. We've had lots of cloudy nights so imaging has been limited. It was -3deg C last night when I took this. Brrrrrrr
Ha has increased n strength with a stronger P Cyg profile.
