Isobel (preliminary ESI): Ia looks good at z~1.1 (night 4 data is best) Possible OII at z=1.12??
Andy (preliminary ESI): I agree, might be Ia at z=1.12. See my median-smoothed comparison to SN 1990N at -7d: Bocc.90n.m14.ps.
Lifan (final ESI?): Could be Ia at z~1.1, or could be Ic at z=0.55. See comments and figures here.
