COMET P/2005 YQ_127 (LINEAR)
     A number of reports have been received describing the cometary
nature of 2005 YQ_127, an object discovered by LINEAR and presumed
asteroidal.  The discovery position (originally published on MPS
156789) is given below, while additional astrometry and a revised
orbit (T = 2005 Nov. 3.96 TT, q = 1.9202 AU, e = 0.5042, P = 7.62
yr, Peri. = 152.32 deg, Peri. = 276.37 deg, i = 16.74 deg, equinox
2000.0) were published on MPEC 2006-A57.  M. Mannucci, N.
Montigiani, and S. Riccetti (Florence, Italy, 0.25-m reflector +
CCD) reported that images taken on Jan. 6.89 and 9.89 UT show a
diffuse coma.

SUPERNOVAE 2006D, 2006E, 2006F
     Three apparent supernovae have been reported from unfiltered
CCD images:  2006D by C. Colesanti, C. Jacques, E. Pimentel, and T.
Napoleao (BRASS survey; cf. IAUC 8589); 2006E independently by
three survey programs [by T. Puckett and V. Reddy (0.60-m automated
supernova patrol telescope; cf. IAUC 8657; source of tabulated data
below); by M. Baek and W. Li (LOSS/KAIT; cf. IAUC 8657); and by M.
Migliardi (Cortina, Italy, 0.5-m "Ullrich" telescope in the course
of the CROSS program; cf. IAUC 7373; communicated via A. Dimai,
Cortina d'Ampezzo, Italy)]; and 2006F by M. Villi (Piacenza, Italy,
also with the CROSS program, and via Dimai).

Additional unfiltered CCD magnitudes of 2006D in MCG -01-33-34:
2005 July 7.85 UT, [19.0; 2006 Jan. 13.12, 15.5.  Also, nothing is
visible at the location of 2006D on a red Palomar Survey plate from
1956.  Additional magnitudes of 2006E in NGC 5338:  2004 Jan. 23,
[19.8 (Puckett); 2005 June 26.25, [19.0 (KAIT); 2006 Jan. 13.15,
14.2 (Migliardi); 13.52, 14.3 (Puckett, remotely with a 0.35-m
reflector at Portal, AZ); 13.58, 14.3 (KAIT).  Li provides position
end figures 28s.52, 22".2 for 2006E; Migliardi provides position
end figures 28s.52, 22".3.  Additional approximate CCD magnitudes
of 2006F in NGC 935:  2005 Nov. 21, [18.5; 2006 Jan. 13.76, 16.7.
SN 2006F is also absent on Palomar Sky Survey infrared, red, and
blue plates.
