BRAZIL TO JOIN THE EUROPEAN SOUTHERN OBSERVATORY
On 2010 December 29, at a ceremony in Brasilia, the Brazilian Minister 
of Science and Technology, Sergio Machado Rezende and the ESO Director 
General, Tim de Zeeuw signed the formal accession agreement aiming to 
make Brazil a Member State of the European Southern Observatory.

Brazil will become the fifteen Member State and the first from outside 
Europe. Since the agreement means accession to an international 
convention, the agreement must now be submitted to the Brazilian 
Parliament for ratification. The signing of the agreement followed the 
unanimous approval by the ESO Council during an extraordinary meeting on 
21 December 2010.

SUPERNOVA 2010kg IN NGC 1633 (LOSS)
2010kg  Nov 29.34   04 40 08.40  +07 21 00.0  18.8   10.5"W,  3.0"N
Spectrum of Dec 1 (Calkins) suggests type-Ia a week before maximum.

SUPERNOVA 2010kh IN UGC 11657 (LOSS)

Pre-discovery by Itagaki, 2010 Nov 21.44UT, 17.3

SUPERNOVAE 2010kj AND 2010kk (Mt. Lemon Survey)
2010kj  Nov  2.32   02 48 37.15  +07 24 10.8  18.5    1  "E,  1  "S
2010kk  Nov  8.36   03 53 23.23  +09 54 33.3  20.2    0.5"W
Spectroscopy of both objects with the SAO's BTA 6-m reflector on Nov 15 
UT indicates each is type-Ia.

SUPERNOVAE 2010kl AND 2010km (CRTS)
2010kl  Nov 16.47   11 27 17.48  +03 45 33.3  18.9    0.3"W, 10.0"N
2010km  Dec  4.33   02 55 12.81  +24 38 13.1  18.8    9.1"E,  3.3"N

SUPERNOVA 2010kn (ROTSE)
2010kn  Dec  2.20   11 50 17.04  +43 57 47.0  18.5    0.2"E,  1.6"N
A spectrum of Dec. 5.45 with the 9.2-m Hobby-Eberly Telescope by M. 
Shetrone, shows it to be a type-Ia supernova, a few days before maximum 
light.

SUPERNOVA 2010ko IN NGC 1954 (Montarrenti)
2010ko  Dec  5.01   05 32 49.44  -14 05 45.9  16.8   15  "E,118  "S
Guy Hurst reports that an image with the Bradford Robotic Telescope on 
Dec 26.04UT gave an unfiltered magnitude measurement of 15.6 indicating 
a brightening since discovery.

A spectrum of Dec. 7 UT by M. Calkins with the F. L. Whipple Observatory 
1.5-m telescope shows the best fit is with the type-Ia supernova 1992A 
when five days before maximum brightness.

J. Parrent et. al., on behalf the "Palomar Transient Factory", also 
report a CCD spectrum with the Gemini South telescope on Dec. 7 UT shows 
it to be of type-Ia close to or before maximum light at an approximate 
redshift of z = 0.01. Further inspection suggests it may be one of the 
subluminous type-Ia supernovae.
