SUPERNOVA 2005lr IN ESO 492-G2
     Further to IAUC 8634, M. Baek and W. Li report the LOSS
discovery of an apparent supernova on unfiltered KAIT images.  SN
2005lr is located at R.A. = 7h11m39s.03, Decl. = -26o42'20".2
(equinox 2000.0), which is 18".8 west and 2".1 south of the nucleus
of the galaxy ESO 492-G2.  Available magnitudes:  2003 Oct. 29.45
UT, [19.5; 2005 Oct. 25.40, [19.0; Nov. 5.41, [18.5; Dec. 4.41,
18.5; 5.39, 18.5.


V2361 CYGNI
     C. C. Venturini, R. J. Rudy, D. K. Lynch, and S. Mazuk,
Aerospace Corporation; R. C. Puetter, University of California at
San Diego; R. B. Perry, Langley Research Center, NASA; and B. Walp,
Lick Observatory, report 0.47- to 2.5-micron spectroscopy of V2361
Cyg (cf. IAUC 8483, 8487) with the Lick 3.0-m telescope (+ VNIRIS)
at Nov. 13.212 UT.  The near-infrared excess has diminished, which
suggests a lowering of the dust temperature.  The object is not as
heavily extincted as was previously observed, probably a result of
dissipation of a dust shell formed after outburst.  The lower-
excitation coronal lines of [Si VI] and [Ca VIII] are present.  He
I 1.0830-microns is dominant and He II lines are present.  [N I] is
identified, and the unidentified novae lines are weakly present.
The optical spectrum is faint, and only H_alpha, [O III], and [N
II] are prominent -- although other weaker features are present.
