V5669 Sgr = NOVA Sgr 2015 No. 3 = PNV J18033275-2816054
     S. Nakano, Sumoto, Japan, reports the discovery by by K.
Itagaki (Teppo-cho, Yamagata, Japan) of an apparent nova (mag 9.9)
in Sagittarius on an unfiltered CCD frame taken on Sept. 27.429 UT
using a 180-mm-focal-length camera lens; confirming CCD images
taken by Itagaki with a 0.50-m reflector yield the following
position for the variable:  R.A. = 18h03m32s.75, Decl. =
-28o16'05".4 (equinox 2000.0).  The variable was designated PNV
J18033275-2816054 when it was posted at the Central Bureau's TOCP
webpage.  E. Kazarovets and N. Samus note that the permanent GCVS
designation V5669 Sgr has been assigned to this variable.
     Additional CCD magnitudes for V5669 Sgr:  Sept. 20.438 UT,
[13.0 (Itagaki); 23.420, [12.5 (Y. Nakamura, Kameyama, Mie, Japan;
communicated by H. Yamaoka, Kyushu Univ.); 27.404, 9.5 (T. Kojima,
Tsumagoi, Gunma-ken, Japan; pre-discovery image; Canon EOS 60
camera + 135-mm-f.l. lens + infrared filter; communicated by
Nakano); 27.418, 27.420, 9.7 (Y. Sakurai, Mito, Ibaraki-ken, Japan;
pre-discovery image; Nikon D7100 camera + 180-mm-f.l. lens;
communicated by Nakano); 27.419, 9.5 (Nakamura; 135-mm-f.l. camera
lens; position end figures 33s.6, 14"; communicated by Yamaoka);
27.441, 9.3 (K. Nishiyama, Kurume, Japan; 0.50-m reflector;
position end figures 32s.74, 05".6; catalogued star of mag 20
located 0".5 to the northwest); 27.447, 10.5 (A. Takao, Kitakyushu,
Japan; independent discovery reported after posting on TOCP
webpage; position end figures 33s.6, 10"); 27.483, 9.8 (T. Noguchi,
Chiba-ken, Japan; 0.23-m reflector; position end figures 32s.75,
05".4; communicated by Nakano); 28.082, B = 9.77, V = 9.18, R_c =
8.83, I_c = 8.48 (S. Kiyota, Kamagaya, Japan; remotely with a
0.43-m astrograph near Mayhill, NM, USA); 28.4, 9.5 (E. Guido;
remotely with an iTelescope 0.43-m astrograph at Siding Spring;
position end figures 32s.77, 05".3).  Selected visual magnitude
estimates for V5669 Sgr:  Sept. 27.50, 10.2 (P. Camilleri, Warners
Bay, NSW, Australia; communicated by E. O. Waagen, AAVSO; variable
noted as red); 27.629, 9.7 (A. Pearce, Nedlands, W. Australia);
27.786, 9.5 (P. Schmeer, Bischmisheim, Germany); 28.478, 9.0
(Pearce; moonlight); 28.736, 8.7 (D. Blane, Henley-on-Klip, South
Africa; communicated by Waagen); 29.714, 9.2 (Blane).
     A spectrogram (resolution about 500 at H_beta) taken of V5669
Sgr by M. Fujii, Kurashiki, Okayama, Japan, with a 0.4-m telescope
on Sept. 27.487 UT shows Balmer emission lines, with the H_beta
line having a P-Cyg profile that indicates an expansion velocity of
about 1100 km/s; emission lines of Fe II (37), (42), and (49) also
have P-Cyg profiles, and Na D absorption is remarkable.
     Additional details are given on CBET 4145.
