Nova Del, Fe lines on the rise.

Nova Del is fading fast, now at 10.2 magnitude.

Nova Del is in its nebular phase so that I'm not sure that your assignment of the Fe I line at 4629 A and [Fe II] lines at 4929 and 5007 A are entirely correct. There certainly is some blending of multiple emission lines, however, I believe the predominant line at 4630 is related to N III while that at 5007 A is associated with [O III]. Perhaps one of the spectroscopy experts that visit this forum can enlighten both of us. For reference, I've included an annotated spectrum taken last night (10 x 90 s) with a low resolution spectrophotometer.

Was the spectra recorded with the DSS-7?

Thank you and yes, this spectrum was obtained with the DSS-7. I've been following Nova Del 2013 since Aug 20th and submitting the spectra to ARAS spectral database. The past two months has been the first sustained use of this equipment since purchasing it 4 years ago.
