A spectrum at 280 days

I see this has now faded to Vmag ~15 so  time for perhaps a last low resolution spectrum.  It shows a nebula type spectrum with strong forbidden emission lines, particularly [OIII] and a very weak almost undetectable continuum (The Y scale is relative to the continuum at 5500A and the signal/noise in the continuum is down in single figures). In fact I estimate 78% of the light in the V passband comes from just the [OIII] pair of lines at 4959/5007 A
