(121) HERMIONE
P. Descamps, Institut de Mecanique Celeste et de Calcul des
Ephemerides (IMCCE), Paris et. al., report on CBET 964 that a 
photometric observation program of the minor planet (121) Hermione 
confirms the bilobated shape of the primary suggested by direct Keck 
adaptive-optics imaging taken in 2003. The system is currently viewed 
edge-on.  The lightcurves recorded mostly at the Make Observatory 
(Reunion Island) over seven nights reveal the high amplitude of the 
brightness variation (up to 0.75), with a morphology typical of a 
contact binary composed of two unequal components with a size ratio of 
about 0.6.

SUPERNOVA 2007cd IN NGC 5174
Discovery by K. Itagaki of a possible supernova (CBET 950):
SN      2006 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2007cd  Apr. 27.61  13 29 26.48  +11 00 44.8  17.5    9"  E,16"  N
An image by Guy Hurst using the Bradford Robotic Telescope on 2007 May 
19 (03h37mUT) did not show the object to a limit of magnitude 17.0

SUPERNOVA 2007ce IN ANONYMOUS GALAXY
Discovery by R. Quimby of a possible supernova (CBET 953):

2007ce  May   4.14  12 10 17.96  +48 43 31.5  17.4    -      -
Type-Ic supernova

SUPERNOVA 2007cf IN MCG +02-39-21
Discovery by Puckett and McDonald of a possible supernova (CBET 954):
SN      2006 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2007cf  May   8.31  15 23 07.66  +08 31 45.5  17.9    3.3"E, 3.1"N
A spectrogram by W. Peters of May 10.29UT indicates type-Ia around one 
week past maximum according to CBET 958.

SUPERNOVA 2007cg IN ESO 508-G75
Discovery by LOSS of a possible supernova (CBET 960):
SN      2006 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2007cg  May  11.34  13 25 33.58  -24 39 08.1  17.7    3.1"E, 0.7"N
A spectrogram of May 14.26UT by W. Brown at F. L. Whipple Observatory 
shows it to be a highly reddened type-Ia supernova then before maximum 
light.

SUPERNOVA 2007ch IN NGC 6000
Discovery by Berto Monard of a possible supernova (CBET 961):
SN      2006 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2007ch  May  11.91  15 49 47.82  -29 23 13.7  17.2   23"  W, 1  "S
A spectrogram by Berlind of May 15.34UT at the F. L. Whipple Observatory 
shows it to be a type-II supernova several weeks past maximum. It may be 
of the plateau sub-type.
