SUPERNOVAE 2002id-2002it
     Further to IAUC 7994, G. Miknaitis, A. Miceli, and A. Garg,
report the SDSS detection of 17 supernovae by subtraction against
images (limiting mag r = 22.5) taken on 2002 Oct. 10 (SNe
2002id-2002ih and 2002ip) and on 2001 Nov. 12 (the rest).  Objects
lacking offsets are < 2" from the cores of their host galaxies.
Spectroscopy was obtained by R. Chornock, S. Jha, A. Filippenko,
and B. Barris with the Keck II (= K2) and Keck I telescopes (= K1)
and by M. Hamuy with the Magellan I telescope (= H), yielding dates
in Nov., spectroscopic types, ages, and redshifts (z):  2002id, 2,
Ia, near maximum, 0.298 (K2); 2002ie, 2, reddened Ia, near max,
0.163 (K2); 2002if, 2, features seen in spectrum (possibly type
Ic), --, 0.321 (K2); 2002ig, 2, young II, --, 0.077 (K2); 2002ih,
3, Ia, a little before max, 0.20 (K2); 2002ii, 8, Ia, just past
max, 0.10 (K1); 2002ij, 8, Ia, just past max, 0.194 (K1); 2002ik,
8, IIp, in plateau phase, 0.032 (K1); 2002il, 9, Ia, about 2 weeks
past max, 0.12 (K2); 2002im, 9, Ia, about 1 week past max, 0.25
(K2); 2002in, 11, II, --, 0.076 (K1); 2002io, 11, Ia, near maximum,
0.25 (K1); 2002ip, 11, II, --, 0.079 (H); 2002iq, 12, II, --, 0.056
(H); 2002ir, 12, Ia, 1-2 weeks past max, 0.28 (H); 2002is, 12, Ia,
1-2 weeks past max, 0.26 (H); 2002it, 12, spectrum shows broad
supernova-like features, --, -- (H).
