     W. Liller, Vina del Mar, Chile, reports his discovery of a
possible nova (mag 8.6) on two Technical Pan films taken on Oct.
1.010 and 1.011 UT with an orange filter.  The new object is
located at R.A. = 13h55m.5, Decl. = -64o16' (equinox 2000.0).
Nothing brighter than mag 11.0 appears at this location on photos
taken by Liller on Sept. 19.00.  A. C. Gilmore, Mount John
Observatory, University of Canterbury, reports the following
photoelectric photometry of the new object obtained with the 0.6-m
f/16 reflector under marginal conditions (thin cloud, bright
moonlight); reference stars were Cousins F218 and F212: Oct. 2.415,
V = 9.11, U-B = +0.83, B-V = +1.41, V-R = +0.81, V-I = +1.69,
airmass 2.18.  Gilmore provides the following position with
uncertainty < 10" in each coordinate (proper astrometry not
possible due to lack of reference stars in the moonlight):  R.A. =
13h55m41s.9, Decl. = -64o15'48" (equinox 2000.0).  Visual magnitude
estimates:  Oct. 2.33, 9.2 (A. Jones, Nelson, New Zealand); 2.542,
9.3 (A. Pearce, Nedlands, W. Australia); 2.708, 9.5 (L. Monard,
Pretoria, S. Africa); 2.993, 9.4 (A. Amorim, Florianopolis,
Brazil); 3.510, 9.6 (Pearce).

SUPERNOVA 2001eo IN UGC 3963
     T. Puckett and M. Marcus, Mountain Town, GA, report the
discovery of an apparent supernova (mag 17.5) on an unfiltered CCD
frame (limiting mag 19.0) taken with the Puckett Observatory 0.30-m
automated patrol telescope on Oct. 1.38 UT.  SN 2001eo is located
at R.A. = 7h41m31s.10, Decl. = +51o41'05".4 (equinox 2000.0), which
is 10".0 west and 13".5 south of the center of UGC 3963.  The new
object was confirmed on CCD frames taken on Oct. 2.34 by Marcus
(0.60-m reflector).  The candidate is not present on images taken
by Puckett on 2001 Mar. 10, 18, and 23 (limiting mag about 20.5),
or on Palomar Sky Survey images taken on 1999 Mar. 6, 1992 Nov. 25
(limiting mag about 21.0), and 1954 Feb. 25 (limiting mag about

COMET C/1996 B4 (SOHO)
