François,

Coincidence, j'ai également fait le spectre de SU Lyn le 9 mai et le 20 avril
Le profil H Alpha évolue avec une partie en emission qui augmente et une partie en absorption qui s'élargie
Image

Le profil H beta quant à lui augmente en intensité mais sans montrer des changements notoires dans le profil.

Here is a LhiresIII spectra, process in Isis, I took last night (02Dec17) centered on Ha:

Here's the 2D, Isis processed image:

Per Peter Somogyi, I added a 2" Lumicon barlow that gives me a 1.67 magnification factor to my F/6.8 system yielding about F/11.4 for better light throughput to the LhiresIII.
I've taken photometry the last month on this object and just took a LISA spectrum tonight (03Dec17). Will post those later after I get some sleep.......

Here are LhiresIII spectra of SU Lyn, processed in Isis, I took over the last few nights in Dec........
Ha(22Dec17):

Ha(15Dec17):

Hb(15Dec17):

CaK (22Dec17):

CaK (19Dec17)resampled with low-pass gaussian:

The Hb seems especially interesting with many ripples and "step-ladder" increases towards the right.........the NeIII(?) line around 3868.76 has decreased in intensity btw the earlier CaK spectra shot and the 22Dec17 spectra. I still have a few more to process that I will display latter.

Here is my latest (01Jan18) low resolution-LISA spectra of SU Lyn:
Image
Nice activity of system. The H-Beta spike seen in the LhiresIII spectrum is of course invisible at this resolution; I included the
H-Beta line to reference with the previous LhiresIII spectra. The H-epsilon absorption is just barely visible..........will shoot this
object again over the next few months.
