    Ah, that's what we originally thought. At this point, I think there is likely to be no problem using
    the FORS2 time between the 15th and 18th of May to get the spectroscopy on every one of the SNe that we
    are following with CFHT. This time just won't be useful for confirming SNe for HST. Depending on how we
    are doing with the next two half-nights at FORS2 and with the upcoming CFHT and CTIO searching, we should
    consider your idea of swapping some FORS2 time for FORS1 time (and try to confirm the two z ~ 0.85 SNe we
    need for HST). How likely do you think it is that ESO would give approval for that?
