COMET C/2003 T2 (LINEAR)
     An apparently asteroidal object reported by LINEAR (discovery
observation below), and posted on the NEO Confirmation Page, has
been found to show cometary appearance by several CCD astrometric
observers, including R. Apitzsch (Wildberg, Germany, 0.24-m
reflector; Oct. 14.0 UT, diffuse coma of diameter about 10"), J. E.
McGaha (Tucson, AZ, 0.62-m reflector; Oct. 14.4, bright compact
coma of diameter 4" with a fainter outer coma of diameter 10" and a
broad tail 20" long in p.a. 30 deg), G. R. Jones (Tucson, AZ,
0.32-m reflector; Oct. 14.4, coma diameter about 6" and a possible
tail at p.a. 35 deg), P. R. Holvorcem and M. Schwartz (Tenagra
0.81-m reflector at Nogales, AZ; Oct. 14.5, co-addition of three
120-s exposures shows a coma of diameter about 15" and total mag
15.1-15.6), and A. Knoefel and T. Payer (Essen, Germany, 0.32-m
reflector; Oct. 14.9, short tail).

The available astrometry, the following preliminary parabolic
orbital elements, and an ephemeris appear on MPEC 2003-T70.

NOVAE IN M31
     Further to IAUC 8165, two apparent novae in M31 have been
discovered by K. Hornoch (Sept. 30.835 UT, R = 17.0, R.A. =
0h42m46s.72, Decl. = +41o19'46".7, equinox 2000.0, or 26" east and
219" north of the galaxy center) and by M. Fiaschi, F. Di Mille,
and D. Tiveron (Oct. 6.908, [H_alpha] = 16.7, R.A. = 0h42m03s.11,
Decl. = +41o14'50".6, or 465" west and 78" south of the galaxy
center).  Additional R-band magnitudes from Hornoch and [H_alpha]
magnitudes by Fiaschi et al. (F) of the object found by Hornoch:
Sept. 26.812, [18.6; 30.835, 17.0; Oct. 1.990, 17.2; 6.908, 16.6
(F); 9.908, 15.7 (F); 12.753, 17.3.  Additional magnitudes of the
second object:  Aug. 22.980 UT, [18.8; 23.971, 18.1; 24.869, 17.4;
26.930, 17.6; 26.976, 16.2 (F); 28.908, 17.8; Sept. 6.933, 18.0;
17.810, 18.3; 21.822, 18.6; 24.928, 18.6; 30.825, [18.6; Oct.
9.908, 16.5 (F).  The apparent nova found by Rector (cf. IAUC
8210) also appears at mag 16.6 on an H_alpha image taken by Fiaschi
et al.
