SUPERNOVA 2003hv IN NGC 1201
     Further to IAUC 8195, B. Beutler and W. Li report the LOTOSS
discovery of an apparent supernova (mag about 12.5) on an
unfiltered KAIT image taken on Sept. 9.5 UT.  The new object was
confirmed at mag about 13.0 on an earlier KAIT image taken on Sept.
1.5.  SN 2003hv is located at R.A. = 3h04m09s.32, Decl. =
-26o05'07".5 (equinox 2000.0), which is 17".2 east and 56".7 south
of the nucleus of NGC 1201.  A KAIT image taken on Jan. 28.2 showed
nothing at this position (limiting mag about 18.0).

SUPERNOVA 2002lt AND GRB 021211
     M. Della Valle, Istituto Nazionale di Astrofisica (INAF),
Firenze; D. Malesani, International School for Advanced Studies,
Trieste; S. Benetti, INAF, Padova; and V. Testa and L. Stella,
INAF, Rome, on behalf of a larger collaboration (see Della Valle et
al. 2003, A.Ap. 406, L33) report the discovery of an apparent
supernova associated with GRB 021211 (Crew et al. 2002, GCN 1734)
on four R images obtained on 2003 Jan. 9.7 (R = 24.48 +/- 0.18,
supernova + host galaxy), 15.33 (R = 25.07 +/- 0.15), Feb. 28.02 (R
= 25.13 +/- 0.12), and Mar. 9.01 UT (R = 25.35 +/- 0.17), with the
Very Large Telescope (VLT; + FORS2) at the European Southern
Observatory.  SN 2002lt is coincident with the position of the
optical afterglow reported by Fox et al. (2003, Ap.J. 586, L5):
R.A. = 8h08m59s.86, Decl. = +6o43'37".5 (equinox 2000.0).
Inspection of a 4-hr integrated VLT spectrum obtained on Jan. 8.27
(27 days after the GRB outburst) confirms the redshift of the
parent galaxy reported by Vreeswijk et al. (2002, GCN 1785) at z =
1.006 and finds broad, low-amplitude undulations blueward and
redward of a broad absorption (FWHM about 15.0 nm), the minimum of
which is measured at 377.0 nm in the rest frame of the GRB (the
blue wing extends up to 365.0 nm).  A comparison with spectroscopic
templates of supernovae (arranged by different spectroscopic types)
strongly supports the identification of the broad absorption with
Ca II H + K, blueshifted by about 15000 km/s.  The most convincing
resemblance is found with the spectra of the 'prototypical' type-Ic
supernova 1994I (Filippenko et al. 1995, Ap.J. 450, L11) obtained
between 0 and 40 days after maximum light.
