SUPERNOVAE 2003kd AND 2003ke
     Further to IAUC 8242, B. Swift, R. Foley, and W. Li report the
LOSS discovery of two apparent supernovae on unfiltered KAIT images:

SN       2003 UT       R.A.  (2000.0)  Decl.    Mag.     Offset
2003kd   Nov. 23.3    3 00 45.80  +44 27 13.0   17.1   0".6 W, 6".7 N
2003ke   Nov. 23.6    9 45 52.96  +34 41 01.4   18.2   9".3 E, 7".0 S

Additional approximate magnitudes:  SN 2003kd in UGC 2468, Oct.
26.3 UT, [19.5; Nov. 24.4, 16.7.  SN 2003ke in MCG +06-22-9, Apr.
4.2, [19.5; Nov. 25.5, 18.3.


SUPERNOVAE 2003kb AND 2003kc
     A. V. Filippenko, R. J. Foley, and B. J. Swift write that
inspection of CCD spectra obtained at Lick, as noted on IAUC 8242,
on Nov. 23 UT reveals that two of the classifications should be
revised; the new spectrograms have considerably higher quality than
did those obtained on Nov. 22, when conditions were poor.  SN
2003kb is probably of type Ic, about 1 week past maximum brightness
(rather than type Ia, about 2 weeks past maximum).  SN 2003kc is a
relatively normal type-Ia supernova near maximum brightness; its
spectrum is not very similar to that of SN 1991T.
