Isobel (preliminary):z=0.28 Type I (from SN features). No SiII dip or galaxy lines.
Andy (preliminary):Probably a Ia judging from blue features. There is a hint of Si 4000, but nothing in red matches. Where is Si 6150? Is there something wrong with the reduction?
Note that although mathematically the best match was at z=0.30 for SN 1990N at -14 days, my program was thrown off by the non-matching data in the red. It is clear from the rest frame Si 4000 line that this SN is later than -14 days. Most other fits get the redshift as z=0.28, so I think that is a better redshift than z=0.30.
Gregory Sainton(final):I agree with you, it's really weird, where is Si @ 6100A ? Could it be a type Ic or anything else. Morover, the magnitude given by the light curve made with the CFHT follow up show that this object is 1.5 magnitude weaker than C02-000. Is it possible to conclude that it's a type Ia, finally, knowing that it's one of the fundamental feature to identify a Type Ia. Really, I don't know.
Andy (final): Even in the new reduction, something is still funny with the data -- you still can't see the Si 6150 line. And now the Si 4000 A line is not as obvious. I estimate z=0.27 for the redshift if it is a Ia. Given Gregory's comments above about the magnitude, and after looking at the lightcurve, I have lost all confidence that this is a Ia. So I have no idea what the redshift is as well.
