SUPERNOVAE 2010jg, 2010jh, AND 2010ji
     Further to CBET 2521, 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
three apparent supernovae in unfiltered Catalina Sky Survey (CSS) images:

 SN       2010 UT        R.A. (2000.0) Decl.      Mag.      Offset
 2010jg   Oct. 11.22   22 04 27.42  - 7 58 41.2   17.9    9".0 E, 2".0 N
 2010jh   Oct. 12.19   22 35 16.47  -21 41 54.1   16.7    0".9 W, 0".1 N
 2010ji   Oct. 17.33    1 45 31.91  +25 32 15.3   17.6    8".0 W, 57".6 N

Further magnitude estimates for 2010jg:  Sept. 12.21, [19.4 (CSS); Oct.
17.06, 18.0 (S. Howerton, Arkansas City, KS, U.S.A., remotely using the LB-1
0.6m telescope at Rodeo, NM).  The presumed host galaxy for 2010jg, SDSS
J220426.80-075843.3, has redshift z = 0.061.  Further magnitude estimates
for 2010jh:  2009 Nov. 17.11, [18.0 (CSS); 2010 Oct. 18.20, 16.9 (J.
Brimacombe, remotely with the RCOS 0.5-m telescope of the New Mexico Skies
Observatory at Mt. Joy, NM).  Further CSS magnitude estimates for 2010ji
(whose presumed host galaxy is UGC 1230):  Oct. 9.38 UT, [19.5; 28.22, 17.5.
