SUPERNOVAE 2006D, 2006E, 2006F, 2006G, 2006H
     Two apparent supernova have been reported from unfiltered CCD
exposures:  2006G by M. Baek and W. Li (LOSS/KAIT; cf. IAUC 8658),
and 2006H by T. Puckett and G. Sostero (0.60-m automated supernova
patrol telescope; cf. IAUC 8658).

SN      2006 UT      R.A.  (2000.0)  Decl.    Mag.     Offset
2006G   Jan. 13.15   1 24 35.83  + 1 43 15.8  17.5  32".4 E, 38".3 S
2006H   Jan. 15.05   3 26 01.49  +40 41 42.5  17.0  4".7 E, 2".2 N

Additional magnitudes of 2006G in NGC 521:  2005 Nov. 22.21 UT,
[19.5; Dec. 14.20, [18.0; 2006 Jan. 13.22, 17.5; 14.12, 17.3.
Additional approximate unfiltered CCD magnitudes of 2006H, whose
offsets above are with respect to the center of a galaxy that
itself is near UGC 2730:  2005 Sept. 23, [19.0 (Puckett); 2006 Jan.
15.77, 16.9 (G. Sostero and S. Garzia on multiple frames taken with
a 0.25-m reflector).  Note that the R.A. offset for 2006H corrects
that on CBET 367.  Supernovae 2006D and 2006E (cf. IAUC 8658) are
type-Ia events (cf. CBET 366), while 2006F (cf. IAUC 8658) is a
type-Ib supernova and 2006G is a type-II supernova (cf. CBET 368).


COMET P/2000 EC_98 = (60558)
     Further to IAUC 8656, K. Kadota (Ageo, Saitama, Japan, 0.25-m
reflector) reports a condensed, bright coma of diameter 1' (total
mag 14.8) and no tail on CCD images taken on Jan. 7.8 UT
(communicated via S. Nakano).  R. Ligustri (Talmassons, Italy,
0.35-m reflector) finds an asymmetric coma of size 1'.3 x 0'.9
extended towards the east in unfiltered CCD images taken on Jan.
9.17 UT.  G. Sostero and E. Guido (remotely using a 0.25-m
reflector near Mayhill, NM) report that R_c-band images taken on
Jan. 10.49 show an uncondensed coma with diameter about 0'.9 and
total mag 14.1, appearing slight elongated in the north-south
direction.  Visual total-magnitude estimates:  Jan. 8.78, 14.4 (S.
Yoshida, Ibaraki, Japan, 0.40-m reflector); 11.53, 14.4 (A. Hale,
Cloudcroft, NM, 0.41-m reflector).


COMET 73P/SCHWASSMANN-WACHMANN
     J. A. Farrell corrects his separations and position angles as
reported on IAUC 8659:  Jan. 6.48831 UT, 1573".7 +/- 0".2 in p.a.
297.78 +/- 0.03 deg; 7.51252, 1598".9 +/- 0".6 in p.a. 297.80 +/-
0.03 deg; 9.39304 (through high clouds), 1644".8 +/- 1".3 in p.a.
297.83 +/- 0.05.
