    Dear Colleagues,
       I've processed the FORS2 data on C-000 and C-001 and I have made a
    preliminary
    assignment of redshifts (see the attached text file).

       Both C-000 and C-001 are at z=1.09 (see the attached plots). We do
    not see the
    SNe (they are too faint), but the hosts are clearly detected. The host
    of C-000 is an
    elliptical (from the spectral point of view); the host of C-001 is a
    galaxy that is actively
    forming stars (again from the spectral point of view).

       There appears to be two clusters in redshift space, one at z=0.97 (at
    least 4 targets) and
    the other at z=1.09 (3 targets). These targets are spread out over
    several arc minutes

       I would like us to discuss two issues at the next teleconference.

    A) Should we submit an ESO DDT proposal to confirm the spectral type of
    these two
    SNe? I would argue yes.

    B) Should we ask for ACS follow-up of selected SNe candidates in the
    HST proposal that
    is currently being prepared?

    Regards, Chris.

    PS These data were taken during full moon, so the data are noisy at
    blue wavelengths.
