SUPERNOVA 2009kp IN NGC 6246
On 2009 Nov 3 an e-mail was received from Tom Boles of Coddenham, 
England reporting the detection of a possible supernova in NGC 6246 
during the course of searches for the UK Nova/Supernova Patrol. The 
object, of magnitude 15.1 was initially detected on Nov 3.819UT and 
subsequently confirmed on Nov 4.724UT using a 0.35-m Schmidt-Cassegrain 
telescope.

The apparent supernova is located at:

RA 16h 49m 51.49s DEC +55 32' 35.8" (2000), which is approximately 
15.0"W and 0.1"S of the centre of the host galaxy.

Nothing is present at this position on Tom's images of 2009 May 23 and 
Aug. 13 (limiting mag 19.5) nor on Digitised Sky Survey plates from 1992 
June 29 (limiting red mag 20.5) and 1990 Apr. 21 (limiting blue mag 
21.0).

The object was designated SN 2009kp and announced on CBET 2004. 
Congratulations to Tom on the discovery of his 127th supernova.

V5584 SAGITTARII = NOVA SAGITTARII 2009 No. 4
N. Samus and E. V. Kazarovets report on that the possible nova reported 
on E-Circular 2593 has been assigned the designation V5584 Sgr by the 
GCVBS team.

H. Maehara, Kwasan Observatory, Kyoto University, advises that a 
low-resolution optical spectrum (range 400-800 nm, resolution about 200) 
of this nova was obtained on Oct. 27.42 UT with the 25-cm telescope of 
the Kwasan Observatory.  The spectrum shows an H-alpha emission line 
that suggests that this object is a classical nova. CCD images of the 
nova yield the following magnitudes:  Oct.
27.460, I_c = 8.66; 27.461, R_c = 9.29; 27.461, V = 9.90; 27.463, B = 
11.06.  Maehara also forwards the report of a spectrogram obtained by M. 
Fujii (Okayama, Japan; 40-cm telescope, range 400- 950 nm) on Oct. 
27.43, showing H_alpha, H_beta, and Fe II lines with P-Cyg features; the 
absorption component of the H_alpha line is blue-shifted from the 
emission peak by 1.5 nm.  These features suggest that this object is a 
classical nova around maximum.  Fujii adds that the Na D line has a 
equivalent width of 0.7 nm.
