Comments:

Isobel (preliminary): This would benefit from some fancy smoothing. Its just possible it has a bump that would make it 0.8ish but I dont know. This has no host and the SN is very faint. Watch out for the 2 gaps between the chips where the spectrum goes to zero.

Andy (preliminary): The fit above is horrible. Nothing is a good fit. I get different answers for the redshift depending on whether or not I use the cleaned (z=0.5) or uncleaned (z=0.9) version of the spectrum. This is not too surprising, because I don't believe any of the fits. If there is any SN signal, I can't see it.
