POSSIBLE SUPERNOVA NEAR NGC 1120
     S. Nakano, Sumoto, Japan, reports the discovery by Koichi Itagaki
(Teppo-cho, Yamagata) of an apparent supernova (mag 17.6) on unfiltered CCD
frames (limiting magnitude 19.5) taken on Aug. 20.696 and 21.777 UT using a
0.60-m f/5.7 reflector (+ Bitran BT-214E camera).  The new object is located
at R.A. = 2h49m10s.81 +/- 0s.01, Decl. = -14d26'59".8 +/- 0".3 (equinox
2000.0), which is 97" east and 65" south of the center of NGC 1120 (but also
near another faint galaxy, so spectroscopy may be necessary to determine the
host galaxy).  Nothing is visible at this position on Itagaki's
past frames (including one from 2000 Nov. 23.60 at limiting mag 19.0) or on
the Digitized Sky Survey.  The discovery image is posted at website URL
http://www.k-itagaki.jp/images/psn-1120.jpg.  Toru Yusa, Osaki, Japan,
reports confirmation of the variable at mag 16.8 on unfiltered CCD frames
(limiting mag 19.0) taken remotely using a 0.25-m f/3.4 refrector (+ SBIG
ST-10XME camera) at the RAS Observatory near Mayhill, NM, U.S.A., on Aug.
21.412, yielding position end figures 10s.78, 59".8.  Yusa has posted his
photograph at URL http://space.geocities.jp/yusastar/PSNinN1120_100821.htm.
