V339 DELPHINI
     R. J. Rudy, E. A. Laag, K. B. Crawford, and M. C. Owens, The Aerospace
Corporation; M. S. L. Moody, The Aerospace Corporation and University of
California at Berkeley; R. C. Puetter, University of California at San Diego;
and R. B. Perry, Langley Research Center, NASA, report on 0.45- to 2.5-micron
spectroscopy of V339 Del (Nova Del 2013) using the The Aerospace Corporation's
Visible and Near-Infrared Imaging Spectrograph on the 3-m Shane reflector at
Lick Observatory.  The object is an "Fe II"-type nova with numerous infrared
Fe II features as well as the signature lines in the visible region.  In
addition, there is strong emssion from C I, N I, O I, and Ca II.  The [O I]
lines are present, including the line at 557.7 nm.  Line widths for the
stronger hydrogen lines are approximately 1300 km/s (FWHM).  The interstellar
reddening, as measured from the O I lines, is E(B-V) = 0.33 +/- 0.1; it is
small compared to the interstellar extinction of most novae.

     Additional visual magnitude estimates (cf. IAUC 9258) reported to the
Central Bureau:  Sept. 3.788 UT, 7.3 (S. Baroni, Milan, Italy); 4.915, 7.0 (E.
Broens, Mol, Belgium); 5.806, 7.4 (Baroni); 6.830, 7.2 (Broens); 7.917, 7.4
(Willian Souza, Sao Paulo, Brazil); 8.863, 7.2 (Broens); 9.042, 7.5 (Souza).
