Probably my final shot at SN2014J taken on 2014-04-17. It is getting very faint for my instrument and the spectrum is pretty noisy.
Seeing was very good so I decided to reduce the spectrum to actual flux.
I used HD89343 at V mag 5.9 as the reference for response.
If I use the Bessel V function on the resulting SN2014J spectrum I get a V magnitude of 13.3.
This is in pretty good agreement with the value on the AAVSO light curve.
