SUPERNOVA 2010kq IN UGC 1769
     Further to CBETs 2547 and 2567, S. Howerton, Arkansas City, KS, U.S.A.;
A. J. Drake, S. G. Djorgovski, A. Mahabal, M. J. Graham, and R. Williams,
California Institute of Technology; J. L. Prieto, Carnegie Observatories; M.
Catelan, Pontificia Universidad Catolica de Chile; E. C. Beshore and S. M.
Larson, Lunar and Planetary Laboratory, University of Arizona; and E.
Christensen, Gemini Observatory, report the CRTS discovery of an apparent
supernova in public images from the Catalina Sky Survey (CSS).

 SN       2010 UT       R.A. (2000.0) Decl.      Mag.      Offset
 2010kq   Dec. 7.23    2 18 10.92  +37 05 42.4   18.3    0".3 E, 4".9 S

After posting on the CBAT's unconfirmed-objects webpage, Markku Nissinen and
Veli-Pekka Hentunen (Varkaus, Finland) report that their exposures (limiting
mag R = 18.9; 3-sigma) taken on Dec. 9 remotely with a 51-cm f/6.8 GRAS011
Global-Rent-a-Scope (+ FLI ProLine PL-11002M camera) near Mayhill, NM, USA,
yield position end figures 11s.05, 39".9 for 2010kq (which is 1".5 east and
6".1 south of the center of the galaxy UGC 1769); they note that nothing is
visible at this position on a red Palomar Sky Survey F plate.  Further CCD
magnitude estimates for 2010kq (unfiltered unless otherwise noted):  Nov.
15.20 UT, [19.5 (CSS); Dec. 9.088, R = 16.4 +/- 0.1 (Nissinen and Hentunen);
9.14, 16.4 (Howerton; remotely using the LB-1 0.6m telescope at Rodeo, NM,
U.S.A.).  Drake notes that the presumed host galaxy, UGC 1769, has redshift
z = 0.027.
