NOVA SCORPII 2014
Further to E-Circular 2992, issued on March 28, the 'transient in Scorpius'
is now re-named 'Nova Scorpii 2014' though will probably be redesignated for
GCVS purposes in due course. 

Additional magnitudes (obtained via CCD unless noted otherwise):  2014 March
27.729, 11.0 (T. Noguchi, Katori, Chiba-ken, Japan; 0.23-m f/6.3
Schmidt-Cassegrain reflector; limiting mag 15.5; position end figures
46s.88, 30".4; reference stars from UCAC4 catalogue; a star of mag 15.8 with
position end figures 46s.87, 30".3 is located on a Digitized Sky Survey
plate taken on 1992 July 21; image posted at URL

Kojima, Gunma-ken, Japan; 150-mm-f.l. camera lens + Canon digital camera +
infrared filter; notes that a star designated 2MASS 17154687-3128303 with
magnitudes J = 11.26, K = 9.58 is located at this position); 27.758, 11.5

Padova, INAF; and S. Dallaporta, ANS Collaboration); 30.707, B = 12.9, V =
11.7, R = 11.2 (T. Yusa, Osaki, Japan; remotely using an iTelescope 0.32-m

31.143, B = 13.60, V = 12.56, R_c = 11.14, I_c = 10.49 (Munari and
Dallaporta).  Selected magnitudes from J. Hambsch, Mol, Belgium (forwarded
by E. O. Waagen, AAVSO):  Mar. 28.417, B = 12.96; 28.418, V = 11.94; 28.419,
I = 9.94; 29.414, B = 13.21; 29.416, V = 12.19; 29.416, I = 10.16; 30.414, B
= 13.32; 30.415, V = 12.35; 30.416, I = 10.33; 31.415, B = 13.72, V = 12.71;
31.416, I = 10.60; Apr. 1.415, B = 14.12, V = 13.05; 1.416, I = 10.89.
Waagen adds that various observations suggest that this may be a symbiotic
nova.

K. Ayani and S. Maeno, Bisei Astronomical Observatory (BAO), Ibara Okayama,
Japan, obtained a low-resolution spectrogram (range 400-800 nm; resolution
0.5 nm at H-alpha) of TCP J17154683-3128303 on Mar. 27.8 UT with the BAO 1-m
telescope.  The spectrum shows broad emission lines of the Balmer series; He
I 501.6-, 587.8-, and 706.5-nm; and probably of O I 777.3-nm. The H-alpha
line has a FWHM of 7000 km/s and EW of about 90 nm.  This indicates that the
variable is a nova in early phase.  Their spectrum is visible via website

Shafter (San Diego State University) leads them to agree that this may be
one of the relatively rare He/N-type novae.

NOVA CYGNI 2014
Further to E-Circular 2993, Bjorn Granslo, Norway reports:
2014 Mar 31.998 UT: Observation: visual mag. 11.3; estimates a-6,b+2 (class
2) Instrument 30.0-cm f/5.3 reflector (x160)
Comparison stars: a = TYC 2672-1791 (mag. V = 10.82, ref.
TASS Mark IV); b = TYC 2672-0929 (V = 11.46, TASS Mark IV).
