V962 CEPHEI = NOVA CEPHEI 2014 = TCP J20542386+6017077
     As first announced on CBET 3825, K. Nishiyama (Kurume, Japan)
and F. Kabashima (Miyaki, Japan) reported the discovery of an
apparent nova (mag 11.7) in Cep on unfiltered CCD frames (limiting
mag 13.7) taken around Mar. 8.79 UT using a 105-mm f/4 camera lens.
The new variable is located at R.A. = 20h54m23s.86, Decl. =
+60o17'07".7 (equinox 2000.0).  The variable was designated TCP
J20542386+6017077 when it was posted at the Central Bureau's TOCP
webpage; N. Samus notes that the permanent GCVS designation V962
Cep has been assigned to this star.  Additional CCD magnitudes for
the variable:  Mar. 3.8405 UT, [13.9 (Nishiyama and Kabashima);
7.781, 12.9 (Nishiyama and Kabashima; pre-discovery; limiting mag
13.8); 8.922, V = 11.90 +/- 0.01 (Arto Oksanen, Hankasalmi,
Finland; 0.40-m reflector; position end figures 22s.60, 08".9);
9.244, B = 12.65, V = 11.62, R_c = 10.76, I_c = 10.02 (S. Kiyota,
Kamagaya, Japan; 0.15-m refractor; position end figures 23s.75,
06".9); Apr. 6.136, 11.9 (G. Masi, Ceccano, Italy; 43-cm reflector,
unfiltered).  U. Munari, Astronomical Observatory of Padova, writes
that spectroscopy obtained on Mar. 9.792 shows that the variable is
a highly reddened "Fe II-type" nova then observed close to maximum
brightness; the spectrum showed strong emission lines from the
Balmer series, O I, Ca II, and Fe II -- all showing width about 800
km/s and having strong P-Cyg absorptions (blue-shifted by 660 km/s
for the Balmer lines).  Additional details are given on CBET 3825.


COMET C/2012 X1 (LINEAR)
     M. L. Sitko, University of Cincinnati and Space Science
Institute; R. W. Russell and D. L. Kim, Aerospace Corporation; and
Eric Volquardsen, NASA Infrared Telescope Facility (IRTF), report
3- to 13-micron spectroscopy of comet C/2012 X1 obtained on the
NASA IRTF (+ Aerospace Corporation's Broadband Array Spectrograph
System) on Apr. 24 UT, when the comet was at r = 1.8 AU.  A
circular aperture of about 4".4 was used; the spectral resolving
power was about 30-120 from 3 to 6.5 microns (resolving power
increasing with wavelength in the CaF_2 prism) and about 30-120
from 6.5 to 13 microns (resolving power increasing with wavelength
in the NaCl prism).  The spectrum exhibited a strong, classic
trapezoidal silicate feature about 50 percent above the graybody
continuum at T = 250 +/- 5 K (normalized to the 8- and 13-micron
regions of the spectrum).  The fitted temperature was about 21
percent above the 207-K equilibrium temperature.  The 10.5-micron
magnitude was +2.9 (+/- 0.1).  An 11.3-micron crystalline-olivine
grain feature was prominently superposed on the trapezoidal
amorphous silicate feature.
