COMET P/2003 U2 (LINEAR)
     F. Shelly, Lincoln Laboratory, Massachusetts Institute of
Technology, reports the discovery of a comet with a diffuse coma
and a very wide, fan-shaped tail in p.a. 85 deg on LINEAR images
(discovery observation below).  Following posting on the NEO
Confirmation Page, other CCD observers have also commented on the
cometary appearance on Oct. 21.1-21.2 UT, including J. Young at
Table Mountain (0.6-m reflector; 5" coma without central
condensation and with a fan-shaped tail about 25" long spanning
p.a. 70-95 deg) and R. Fredrick and T. Medlock at Louisburg, KS
(0.75-m reflector; 30" tail in p.a. 80 deg).

observations on Sept. 19 and Oct. 2), the following orbital
elements, and an ephemeris appear on MPEC 2003-U38.

SUPERNOVA 2003ix IN UGC 3746
     The Lick Observatory Supernova Search program (cf. IAUC 6627),
which is led by A. V. Filippenko and W. Li (and currently includes
B. Beutler, J. Burket, M. Ganeshalingam, J. Graham, H. Pugh, M.
Moore, D. Singer, B. Swift, and D. Weisz), reports (via Li) the
discovery by Ganeshalingam of an apparent supernova (mag about
18.8) on unfiltered KAIT images taken on Oct. 19.5 and 20.5 UT.
The new object is located at R.A. = 7h14m25s.72, Decl. =
+55o08'53".4 (equinox 2000.0), which is 7".0 west and 1".1 south of
the nucleus of UGC 3746.  A KAIT image taken on Apr. 7.1 showed
nothing at this position (limiting mag about 19.5).
