    Dear Chris,

    Thank you very much for your quick suggestions.

    I update the draft.

    >- There appears to be some strange characters associated with the listing
    >for SuF02-005
    I hope I fixed this correctly. The characters must be blank in Japanese
    fonts, and it is hard for me to see those characters with my PC.

    Best regards,

      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 with GMOS on Gemini-N on
    Nov. 6, 8, and 9; with ESI on KeckII on Nov. 6, 7, 9,
    and 10; with FORS2 on Yepun (VLT-UT4) on Nov. 7 - 11; and
    with FOCAS on Subaru on Nov. 12. Redshifts were obtained for 19
    SNe using either the host galaxy spectrum or with template spectrum
    fitting of SN.
