COMET C/2003 R1 (LINEAR)
     An apparently asteroidal object reported by LINEAR (discovery
observation below), and posted on the NEO Confirmation Page, has
been reported to have cometary appearance on CCD images obtained by
J. Ticha and M. Tichy (Klet, 1.06-m KLENOT telescope; slightly
diffuse object with a 6" coma on Sept. 5.08 UT, and asymmetric coma
to the northwest on Sept. 6.05); and by J. E. McGaha (Tucson, AZ,
0.30-m f/10.0 Schmidt-Cassegrain reflector; 3" coma with a fan-
shaped tail 8" long in p.a. 320 deg on Sept. 6.39).

The available astrometry, the following preliminary parabolic
orbital elements, and an ephemeris appear on MPEC 2003-R35.

POSSIBLE NOVA IN M33
     M. Ganeshalingam and W. Li, University of California at
Berkeley report the discovery via LOTOSS (cf. IAUC 8192) of an
apparent nova on unfiltered KAIT images on Sept. 1.4 (mag about
16.9), 4.4 (mag about 17.0), and 6.4 UT (mag about 17.1).  The nova
is located at R.A. = 1h33m51s.16, Decl. = +30o39'50".2 (equinox
2000.0), which is 3".3 east and 14".4 north of the nucleus of M33
(= NGC 598).  A KAIT image taken on Aug. 24.4 showed nothing at
this position (limiting mag about 19.5).

     On IAUC 8188, epsilon INDI B, final sentence, the numbers are
simple brightness ratios, as a fraction of the brightness of
epsilon Ind B, not as a percentage of the brightness of epsilon
Ind B.
