     Veli-Pekka Hentunen and Markku Nissinen, Varkaus, Finland, report their
discovery of an apparent supernova (mag 17.9 +/- 0.2) on a 200-s Bessel-R
image (limiting R mag 19.4) taken with a 36-cm Celestron XLT OTA telescope (+
SBIG ST8 XME camera) on Sept. 15.80 UT, with a confirming image taken on Sept.
17.75.  The new object is located at R.A. = 13h30m10s.54, Decl. = +80o30'26".8
(equinox 2000.0), which is 31" east and 18" north of the center of UGC 8520.
A. Oksanen, Muurame, Finland, reports that he obtained a confirming 60-s
unfiltered CCD image (limiting mag 19.9) of 2009iy on Sept. 19.848 with a
40-cm reflector, finding the new object at mag 18.5 with position end figures
10s.60, 27".1; he has posted his image at the following website URL:
