SATELLITES OF SATURN
     Further to IAUC 8523, S. S. Sheppard, D. C. Jewitt, and J.
Kleyna report the discovery of nine new satellites of Saturn
(S/2004 S 19 and S/2006 S 1-S/2006 S 8) in data obtained during
2004 Dec.-2005 Mar. and 2006 Jan.-Apr. with the Subaru 8.2-m
reflector, aided by B. G. Marsden's ongoing linkages and search
ephemerides.  The astrometry and orbital data appear on MPECs
2006-M44, 2006-M45, and 2006-M48, showing retrograde orbits with
orbital periods ranging from 862 to 1300 days.


SUPERNOVAE 2006dj, 2006dk, 2006dl
     Three additional supernovae have been discovered on unfiltered
CCD images:  2006dj and 2006dl by M. Baek and W. Li (LOSS/KAIT; cf.
IAUC 8725), and 2006dk by M. Migliardi (communicated by A. Dimai;
cf. IAUC 7373).

Additional KAIT magnitudes for 2006dj in UGC 12287:  2000 Oct. 7.24
UT, [20.0; 2006 June 25.46, 18.9; 26.43, 18.9.  Additional CROSS
magnitudes for 2006dk in NGC 4161:  Jan. 30, [18.5; June 26.87,
16.2.  Nothing appears at the location of 2006dk on Palomar Sky
Survey infrared, red, and blue plates.  A spectrogram obtained on
June 26.92 shows that SN 2006dk is a type-II supernova close to the
time of explosion (details on CBET 565).  Additional magnitudes for
2006dl in MCG +04-31-5:  June 19.26, [19.5; 30.23, 18.0.


COMETS C/2006 J12 AND C/2006 K6 (SOHO)
     Additional Kreutz sungrazing comets have been found on SOHO
website images (cf. IAUC 8724; GS = G. Sun) -- both described by K.
Battams as being small and stellar in appearance, with no tails.
C/2006 K6 reached mag 6.5 on May 17.246 UT at 5.5 solar radii in C2
images.
