SUPERNOVAE 2006qs-2006sr
     Fifty-one supernovae discoveries have been reported from
survey images:  2006qs-2006ry by the "Nearby Supernova
Collaboration" (details on CBET 768; magnitude range R = 16.1-20.2),
2006rz by the Sloan Digital Sky Survey II collaboration
(communicated by J. Frieman; details on CBET 770; magnitude g =
20.0), and 2006sa-2006sq by the ESSENCE project (communicated by P.
Challis; details on CBET 772; magnitude range R = 20.8-23.5).  All
are type-Ia supernovae except 2006qt, 2006rc, and 2006rx (type IIn);
2006rh, 2006rj, 2006rk in MCG +05-17-19, 2006rp, 2006rq, 2006rt,
2006ru, and 2006ry (type II); 2006sa (type IIp); and 2006sg (type
Ic).  SN 2006rs appears to be associated with IC 28.  Those objects
brighter than mag 18.8 at discovery are tabulated below.  SN 2006sr
was discovered by D. Rich (Hampden, ME, U.S.A.) on unfiltered CCD
frames taken with a 0.31-m reflector.  Additional magnitudes for
2006sr in UGC 14:  Oct. 1991, [20.2 (Digitized Sky Survey, red);
Aug. 1993, [19.9 (DSS, blue); 2006 Nov. 21.99 UT, [18.6 (Rich); Dec.
15.03, 16.9 (Rich).

COMET P/2006 W1 (GIBBS)
     Additional observations of this comet (cf. IAUC 8775) have
shown it to be of short period, the elements below taken from MPEC
2006-X40:

     T = 2006 Mar. 25.784 TT          Peri. = 229.906
     e = 0.68718                      Node  = 153.814   2000.0
     q = 1.70086 AU                   Incl. =  19.101
       a =  5.43716 AU     n = 0.077740     P =  12.7 years


COMET 182P/LONEOS
     The recovery of comet P/2001 WF_2 = 2006 W2 (cf. IAUC 8776)
has permitted its numbering as comet 182P/LONEOS (cf. MPC 58065).
