Additional CCD magnitudes Jun 18.898, 16.3 (G. Masi; remotely using a 43-cm
telescope at Ceccano, Italy; position end figures 35s.08, 14".7); 19.235,
17.4 (J. Brimacombe, Cairns, Australia; position end figures 35s.22, 15".2.

D. C. Leonard, San Diego State University and others, 2015 Advanced Teen
Astronomy Camp, report on optical spectroscopy obtained with the 2.3-m Bok
telescope at Kitt Peak on June 21 UT.  SN 2015Q is a type-Ib supernova;
cross- correlation with a library of supernova spectra using the comparison
tool GELATO finds good matches with near-maximum type-Ib supernovae at a
redshift of 0.008, consistent with the NED redshift of the putative host
galaxy, NGC 3888.

Nothing is visible at this position on digitized plates of the Palomar Sky
Survey from 1993 May 12 (F plate; limiting magnitude 20.3) and 1996 Mar. 24
(J plate; limiting magnitude 20.3).

S. Benetti et. al., Osservatorio Astronomico di Padova, report that an
optical spectrogram obtained on Apr. 11.90 UT with the Asiago 182-cm
Copernico Telescope in the framework of the Asiago Transient Classification
Program shows that this object is a type-II supernova.  Adopting for the
host galaxy a recessional velocity of 6938 km/s, the expansion velocity of
the ejected material, as inferred from the position of the absorption of the
H_alpha, is about 7800 km/s.

V1534 SCORPII = NOVA SCORPII 2014 = TCP J17154683-3128303
As announced on TA E-Circular 2992 and 2994 K. Nishiyama (Kurume, Japan) and
F. Kabashima (Miyaki, Japan) discovered a possible nova (mag 10.1) on CCD
frames (limiting magnitude 13.4) taken around Mar. 26.85 UT using a 105-mm
f/4 camera lens; confirming frames (limiting mag 16.1) taken around Mar.
26.87 using a 0.40-m reflector yielded position R.A. = 17h15m46s.83, Decl. =
-31o28'30".3 (equinox 2000.0). 

E. Kazarovets and N.Samus note that the permanent GCVS designation V1534 Sco
has been assigned to this variable.
