SUPERNOVAE 2007cr-2007cv
     Further to IAUC 8851, additional apparent supernovae have been
discovered on CCD frames:  2007cr and 2007cv by A. Klotz (0.25-m
'TAROT' robotic telescope, La Silla; R-band indicated), and the
rest by W. Li (LOSS, unfiltered KAIT; with D. Winslow for 2007cs,
and with N. Joubert for the rest).  Discovery observations for
objects brighter than mag 17:

SN      2007 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2007cr  June 16.30  16 21 56.5   -60 40 24    15.0  20" E, 15" S

Telegrams:  2007cr in ESO 137-19, CBET 985; 2007cs in UGC 12798,
CBETs 986 and 987 (type-Ia, discovered some two weeks after
maximum); 2007ct in NGC 6944A, CBETs 988 and 994 (mag 18.1 on June
28; type-II); 2007cu in UGC 10214, CBETs 988 and 994 (mag 18.9 on
June 27; type-II); 2007cv in IC 2597, CBET 989.


COMETS 189P/NEAT AND 190P/MUELLER
     Comet P/2007 N2 = P/2002 O5 (cf. IAUC 8856) has been given the
permanent number 189P, and comet P/2007 O2 = P/1998 U2 (cf. IAUC
8859) has been given the permanent number 190P (cf. MPC 60237).


COMET P/2007 N1 (McNAUGHT)
     Additional observations have shown this comet (cf. IAUC 8855)
to be of short orbital period, as indicated by the following
orbital elements (from MPC 60281):

     T = 2007 Sept.15.892 TT          Peri. = 275.699
     e = 0.38791                      Node  = 105.867   2000.0
     q = 2.03021 AU                   Incl. =   8.721
       a =  3.31687 AU     n = 0.163159     P =   6.04 years


SATURN XLIV (HYRROKKIN)
     The IAU Working Group on Planetary Science Nomenclature has
voted to change the spelling of the name of Saturn XLIV from
'Hyrokkin' (as announced on IAUC 8826) to 'Hyrrokkin'.
