SUPERNOVAE 2003jb, 2003jc, 2003jd, AND 2003je

Four apparent supernovae have been discovered on unfiltered
CCD images:  2003jb by R. Arbour (cf. IAUC 8205), and the rest by
LOSS/KAIT (cf. IAUC 8231, via J. Burket, B. Swift and W. Li).

SN       2003 UT        R.A.  (2000.0)  Decl.   Mag.     Offset
2003jb   Oct. 23.84   14 49 22.28  +63 16 06.2  16.5   4".6 E, 8".0 S
2003jc   Oct. 24.2    23 04 53.34  - 6 32 12.1  17.0   20".2 W, 6".6 N
2003jd   Oct. 25.2    23 21 03.38  - 4 53 45.5  16.1   8".3 E, 7".7 S
2003je   Oct. 25.5     8 49 22.24  +36 42 56.6  18.1   3".7 W, 19".8 N

The above astrometry for SN 2003jb in IC 1065 is by D. Briggs,
Portsmouth, England, from an image obtained with a 0.60-m reflector
on Oct. 24.911 UT (estimated mag approximately 15.9); Arbour's own
position end figures, obtained from an image taken in more inferior
conditions, are 21s.98, 08".6.  Arbour adds that SN 2003jb is not
present on his image taken on Oct. 17.88 or on Digitized Sky Survey
images (limiting magnitudes fainter than 20.0 from a blue plate and
18.5 from a red plate).  Additional approximate KAIT magnitudes: SN
2003jc in MCG -01-58-18, Oct. 5.2, [18.5; 25.2, 16.9.  SN 2003jd in
MCG -01-59-21, Oct. 16.2, [19.0; 26.2, 16.0.  SN 2003je in NGC 2668,
Oct. 15.5, [19.0; 26.5, 17.9.
