(5481) KIUCHI
P. Kusnirak and P. Pravec, Ondrejov Observatory et. al., report on
CBET 1320 that photometric observations obtained during Mar. 13 to Apr. 
6 reveal that minor planet (5481) is a binary system with an orbital 
period of 20.90 +/- 0.01 hr.
The primary shows a period of 3.6196 +/- 0.0002 hr, and it has a
lightcurve amplitude of 0.10 mag, suggesting a nearly spheroidal shape.

M. A. Malkan, University of California et. al., report that inspection 
of a CCD spectrum of Apr. 1 UT with the Shane 3-m reflector, at Lick 
Observatory, shows that 2008bn is a young type-II supernova.

SUPERNOVA 2008bo IN NGC 6643
Discovery by Markku Nissinen, Finland of a possible supernova (CBET 
1324):
SN      2008 UT      R.A.  (2000.0)  Decl.    Mag.     Offset

Arto Oksanen, Finland, adds that his unfiltered CCD exposures taken
with a 40-cm telescope on Apr. 1.050 and 2.788 yield red magnitudes 16.5 
and 16.3, and position end figures 54s.40 +/- 0s.02, 21".4 +/- 0".2.

SUPERNOVA 2008bp IN NGC 3095
Discovery by CHASE project of a possible supernova (CBET 1326):
SN      2008 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
