Chris (preliminary): Most likely a type Ia at z~0.55.
Isobel (preliminary): OII at z=0.553 SNIa features match well. See bruch_snz.ps.
Chris (final): Ia z=0.552 OII
Andy (final): I agree, beautiful, roughly s=1 SN near max. See the comparison to 94D at +5 days at: S01-007.92a.p05.ps These data have been S-G smoothed. It is interesting that Bruch also has 3 peaks like Bizet from 6000 to 6500 A observed.
