SATELLITES OF JUPITER
     Further to IAUC 8088, S. S. Sheppard reports the discovery of
four additional satellites of Jupiter, found on CCD images taken at
Mauna Kea during Feb. 6-Mar. 7.  The astrometry, orbital elements
by B. G. Marsden, and ephemerides appear on MPEC 2003-E29:  S/2003
J 9, e = 0.27, i = 164 deg, P = 684 days, H = 17.2; S/2003 J 10, e
= 0.21, i = 164 deg, P = 768 days, H = 16.7; S/2003 J 11, e = 0.22,
i = 164 deg, P = 682 days, H = 16.8; S/2003 J 12, e = 0.38, i = 146
deg, P = 533 days, H = 17.2.  In revision to IAUC 8087, further
calculations (also given on MPEC 2003-E29) suggest alternative
retrograde orbits for S/2003 J 1 (e = 0.34, i = 163 deg, P = 783
days) and for S/2003 J 6 (e = 0.16, i = 156 deg, P = 618 days).


SUPERNOVAE 2003bo, 2003bp, AND 2003bq
     Three apparent supernovae have been found on unfiltered CCD
images -- SN 2003bo by W. M. Wood-Vasey et al. (cf. IAUC 8088;
Palomar NEAT images), SN 2003bp by D. Hutchings and W. Li (LOTOSS,
via KAIT images; cf. IAUC 8086), and SN 2003bq by T. Boles (cf.
IAUC 8086).

Additional approximate magnitudes from the respective discoverers
(those denoted 'NEAT' are from Wood-Vasey):  SN 2002bo, 2002 Nov.
24.52, [20.2; 2003 Mar. 3.28, 19.5.  SN 2002bp in NGC 2596, Feb.
19.2, [19.0; 28.3, 18.2 (NEAT); Mar. 6.1, 17.8 (NEAT); 7.2, 17.8.
SN 2003bq in UGC 3513, Feb. 17, [19.5; Mar. 7.791, 18.7.  SN 2003bq
is also absent from Palomar Sky Survey red and blue plates.  SN
1998fa also appeared in UGC 3513.
