Hi Kevin,

I have just seen that the iPTF team have now classified it (type 1a) so no need to go for it, unless you want to of course.

Interestingly the “SED machine” spectrograph they use is even lower resolution than mine. They are definitely a rival 😉

The location looks spot on to me in CdC if I overlay the DSS image so probably an epoch issue. (The TNS coordinates are J2000). It is quite close to the galaxy core though so separating it from the galaxy could be a problem.
