SUPERNOVA 2007kf
     W. Kloehr, Schweinfurt, Germany, reports his discovery of an
apparent supernova (mag about 17.0) on unfiltered CCD images (limiting
mag about 18.5) taken on Sept. 22.93 UT with a Meade 0.25-m reflector.
The new object is located at R.A. = 17h31m31s.76, Decl. = +69o18'40".1
(equinox 2000.0), which is 5'.17 west and 1'.57 south of UGC 10911 and
apparently associated with an anonymous galaxy.  Nothing is visible at
this position on Kloehr's reference image from 2006 Sept. 23 (limiting
mag about 18.5) or on a Palomar Sky Survey image (no limiting magnitude
information or date provided).  SN 2007kf also appeared at mag about
16.9 on a composite image (limiting mag 20.5) from ten frames taken by
Kloehr on Sept. 23.82.  The discovery image is available at Kloehr's
website at URL http://www.dsi-astronomie.de/UGC10911.htm.
     R. Arbour, South Wonston, Hants, U.K., reports that he obtained
five unfiltered confirming CCD images of 2007kf beginning at Sept.
24.845 UT using a 0.4-m f/5 reflector (+ Starlight Xpress camera;
limiting mag 19.1), yielding mag 17.2 and position end figures 31s.23,
39".8 (offset from apparent host galaxy 2".2 east, 4".9 south).
