SUPERNOVA 2008hi IN MCG -01-2-15
     S. Nakano, Sumoto, Japan, reports the discovery by Yoshimi Ichimura
(Yoshimi-machi, Hiki-gun, Saitama-ken, Japan) of an apparent supernova (mag
15.2) on 120-s unfiltered CCD frames (limiting mag 18.8) taken around Nov.
21.54 and 22.574 UT using a 0.28-m f/8.1 Schmidt-Cassegrain reflector.
Ichimura measured position R.A. = 0h26m43s, Decl. = -3o35'56' (equinox 2000.0)
for the new object.  A careful measurement by Nakano of Ichimura's BMP image
yields mag 15.4 and R.A. = 0h26m43s.00, Decl. = -3o35'53".4, which is 8" west
and 3" south of the center of MCG -01-2-15; Nakano adds that there is some
uncertainty in both position and brightness of 2008hi because of the host
galaxy's background light, nothing that the new object is about the same
brightness as some nearby 15th-mag foreground stars.  Ichimura notes that
nothing is visible at this position on his frame taken on 2005 Dec. 19
(limiting mag 18); Nakano adds that nothing is visible at this position on
Palomar Sky Survey red and infrared images.  Nakano also reports that K.
Itagaki (Yamagata, Japan, 0.60-m reflector + unfiltered CCD) measured mag
15.5 and position end figures 43s.16, 55".3 for 2008hi from his image taken
on Nov. 22.358.
