Dear all,
Here is a revised draft for the IAUC for last fall run.
Based on discussions on LBNL-Japan meeting last week,
SuF02-81, 12, 83 were moved to the category "not confirmed
with spectroscopy". There may be still some. We also add
SuF02-05.
Do we include HST follow-up information?
Please give us any suggestions, comments,
-Mamoru and Naoki

M. Doi, Univ. of Tokyo, on behalf of the Supernova Cosmology
Project (cf. IAUC 7763 and 7764, plus V. Prasad, G. Sainton, E.
Smith, and A. Spadafora) and the Subaru high-redshift supernova
search group (N. Yasuda, N. Kashikawa, K. Motohara, T. Morokuma,
K.Sekiguchi, G. Kosugi, H. Furusawa, Y. Komiyama, T. Takata,
M. Ouchi, Y. Ohyama, and Subaru Observatory SXDS Project members),
reports the discovery of possible 29 supernovae found with Subaru
telescope +prime-focus Suprime-Cam in SDSS i' band. Reference
images were taken on Sep. 30 and Oct.1, 2002. The limiting magnitude
of reference images was about 26.6mag (S/N=5 for 2arcsec aperture).
We took search images on Nov. 3. The magnitude increase of the
SNe compared with the images in the reference are given in the
table below (photometric accuracy 0.1-0.2mag).
Follow-up photometry was carried out with Suprime-Cam, and we
confirmed SN signals at least 3 epochs among 7
(Nov.3,6,10,28,30,Dec.7,8) for 30 SNe below.
The supernova spectra were obtained at the Gemini telescope on
Nov. 6, 8, and 9; at the KeckII Telescope on Nov. 6, 7, 9, and 10;
at the Very Large Telescope on Nov. 7 - 10; and at the Subaru
telescope on Nov. 12. Redshifts were obtained for 19 SNe
using either the host galaxy spectrum or with template spectrum
fitting of SN.
