     W. Liller, Vina del Mar, Chile, reports his discovery of an
apparent nova (mag approximately 11.5) located at R.A. = 5h10m.6,
Decl. = -69o13' (equinox 2000.0), which is near the compact cluster
NGC 1856, on two unfiltered Technical Pan films taken on Nov.
26.164 UT with a 0.2-m Schmidt camera; the new object is also
present at mag about 12.8 on a film taken on Nov. 22.065.  Nothing
brighter than mag 13 appears at this position on earlier
photographs, the most recent taken on Nov. 20.  Liller forwards the
following precise position measured by B. Allen (Blenheim, New
Zealand) from a CCD image taken on Nov. 27.41:  R.A. = 5h10m33s.79,
Decl. = -69o12'35".2 (V = 12.6; reference star GSC 9161.746) --
showing clearly that the new object is not coincident with any star
visible on Palomar Sky Survey or Digitized Sky Survey images
(limiting mag about 20).  Visual magnitude estimate by A. Pearce,
Nedlands, W. Australia:  Nov. 27.576, 12.8.
     F. M. Walter, Stony Brook University; A. Pasten, Cerro Tololo
Interamerican Observatory (CTIO); and H. E. Bond, Space Telescope
Science Institute, report that a low-resolution spectrogram (range
610-950 nm; resolution 0.86 nm) of Liller's new object, obtained on
Nov. 28.28 UT with the SMARTS/CTIO 1.5-m telescope (+ RC
spectrograph), shows strong H_alpha emission (equivalent width -4.1
nm).  O I 777.4- and 814.6-nm lines show P-Cyg profiles, and the Ca
II infrared triplet is seen in emission.  The new object thus
appears to be a classical nova near maximum.

SUPERNOVAE 2005kv-2005kx
     The discoveries of three apparent supernovae have been
reported from unfiltered CCD frames:  2005kv and 2005kw by the
"Nearby Supernova Factory" collaboration from NEAT images, and
2005kx by T. Puckett and J. Tigner from a frame taken with the
0.35-m automated supernova patrol telescope (cf. IAUC 8630) in
Ellijay, GA.  SNe 2005kv and 2005kw are type-Ia supernovae,
approximately 1 month past maximum and near maximum, respectively
(details on CBET 306).  Additional approximate magnitudes for SN
2005kx in NGC 3197:  Nov. 1, [20.0; 27.00 UT, 17.2 (0.60-m
