NOVA SCORPII 2013 =3D PSN J17335943-3606216
     Koichi Nishiyama, Kurume, Japan; and Fujio Kabashima, Miyaki, Japan,
report their discovery of a possible nova (mag 11.1) in Sco on two
unfiltered
40-s CCD frames taken around June 3.6146 UT (limiting magnitude 13.5) using
a
105-mm f/4 camera lens (+ SBIG STL6303E camera); they confirmed the object
on
five 3-s unfiltered CCD frames taken around June 3.6728 (limiting magnitude
17.4) using a Meade 200R 0.40-m f/9.8 reflector (+ SBIG STL1001E camera).
The new object is located at R.A. =3D 17h33m59s.43, Decl. =3D -36d06´21".6
(equinox 2000.0).  The variable was designated PSN J17335943-3606216 when i=
t
was posted at the Central Bureau´s TOCP webpage.  Additional CCD magnitudes
for the variable:  May 17.694, [13.4 (Nishiyama and Kabashima); 30.647,
[13.4
(Nishiyama and Kabashima); 3.589, I_c =3D 10.39 (Seiichiro Kiyota, Tsukuba,
Japan; 85-mm f/2 camera lens + ST-10XME CCD camera); 3.628, 11.9 (Akira
Takao,
Kitakyushu, Japan; survey images taken with a 100-mm-f.l. f/4 camera lens +
unfiltered STL-6303E camera); 3.7, 11.5 (Ernesto Guido and Nick Howes;

,
Brazil, reports visual mag 11.3 on June 3.992 using an 0.18-m reflector.

     Christian Buil, Castanet, France, reports that he obtained spectroscop=
y
of PNV J17335943-3606216 on June 3.960 UT with an Alpy 600 spectrograph (R =
=3D
600) on a 0.2-m telescope; the spectrum shows a very reddened object, with
an
intense H-alpha emission line (equivalent width 2.9 nm; FWHM =3D 1200 km/s)=
,
indicating a probable nova.  His spectrum can be viewed at website URL
http://tinyurl.com/lgc2r99.  E. Waagen, AAVSO, also reports that Terry
Bohlsen
(Armidale, NSW, Australia) acquired a spectrogram on June 4 that "is
consistent with a nova and similar to C. Buil´s spectra"; Bohlsen obtained
magnitude V =3D 13.5 at the time of the spectroscopy, adding that the varia=
ble
is much brighter in bands R and I.
