Saul (preliminary): z = 1.00 +/- 0.02 based on a pretty nice looking smoothed spectrum (SN Ia, we think)
Andy (preliminary): Ia at z=1.0 is likely but not certain (no Si). My program thinks it may be a few days after max. You can see Si in Lifan's heavily smoothed/binned spectrum, but it looks a little odd.
Gaston (preliminary): SN wiggles compatible with Keck' spectrum and z~1
Peter (preliminary): This one has a good Keck Spectrum of a SN Ia all by itself. Redshift looks to be ~1.0 and one can even see the Si line. It is good to go for all HST observations and the grism wouldn't present any problems.
Andy (preliminary): If the Si that Peter is talking about is not a smoothing artifact, then this one is a good candidate. After taking a better look at the raw data, that Si "feature" near 8000A looks too wide to be Si. Still, this is one of our best candiates.
Chris (Chris final reduction): z=1.03 from SN
