SUPERNOVA 2003hp IN UGC 10942
     Further to IAUC 8184, M. Moore and W. Li report the LOTOSS
discovery of an apparent supernova (mag about 18.4) on unfiltered
KAIT images taken on Aug. 25.2 and 27.2 UT.  SN 2003hp is located
at R.A. = 17h40m18s.69, Decl. = +51o01'41".3 (equinox 2000.0),
which is 17".2 east and 4".8 south of the nucleus of UGC 10942.  A
KAIT image taken on Aug. 17.2 UT showed nothing at this position
(limiting mag about 19.5).

epsilon INDI B
     K. Volk, Gemini South Observatory (GSO), La Serena; R. Blum,
Cerro Tololo Interamerican Observatory, La Serena; G. Walker,
University of British Columbia; and P. Puxley, GSO, report their
detection of a faint companion to the nearby brown dwarf epsilon
Ind B (Scholz et al. 2003, A.Ap. 398, L29) on Aug. 18 and 20 with
the Acquisition Camera and the Phoenix spectrometer at GSO.  The
separation is 0".62 +/- 0".02 in p.a. 133.4 +/- 0.5 deg in
1.28-micron narrowband images, corresponding to a projected
separation of 2.1 AU at the distance of epsilon Ind B.  Due to its
large proper motion, epsilon Ind B is 17".6 from its discovery
position, or now at R.A. = 22h04m12s.415, Decl. = -56o47'05".66
(equinox 2000.0); there is nothing at this position in the
1999.855-epoch 2-MASS J-band image on which epsilon Ind B was
discovered.  The companion is bright enough to have been detected
(at S/N = 300) in the 2-MASS image if it is a background star; this
fact and its unusual colors lead the authors to tentatively
identify it as a late T-type brown dwarf (cf. Burgasser et al. 2002,
Ap.J. 564, 421; Geballe et al. 2002, Ap.J. 564, 466) or a large
planet.  The following relative brightnesses of the new object (as
a percentage of the brightness of epsilon Ind B) were measured from
I-band and various narrowband Phoenix filters:  I approximately
0.25; [1.083 microns], 0.53; [1.282 microns], 0.65; [1.556 microns],
0.29; [2.106 microns], 0.17; [2.321 microns], < 0.03.

     W. Liller, Vina del Mar, Chile, reports the following
magnitudes for this star (cf. IAUC 8185):  Aug. 22.008 UT, V = 9.91
+/- 0.02 (CCD); 22.009, B = 11.16 +/- 0.05 (CCD); 22.996, R = 9.3
+/- 0.1 (red photographs).
     Visual magnitude estimates:  Aug. 22.905 UT, 10.3 (R. Y.
Shida, Sao Paulo, Brazil); 23.931, 10.1 (J. G. S. Aguiar, Campinas,
Brazil); 24.910, 10.0 (Aguiar); 25.542, 10.3 (A. Pearce, Nedlands,
W. Australia); 26.510, 10.5 (Pearce).
