Re: SU Lyn Call for observations by Katarzyna Drozd
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
Le profil H beta quant à lui augmente en intensité mais sans montrer des changements notoires dans le profil.

Re: SU Lyn Call for observations by Katarzyna Drozd
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.......

Re: SU Lyn Call for observations by Katarzyna Drozd
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.

Re: SU Lyn Call for observations by Katarzyna Drozd
Here is my latest (01Jan18) low resolution-LISA spectra of SU Lyn:
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.

Re: SU Lyn Call for observations by Katarzyna Drozd
Here are my latest SU Lyn Spectra (Ha & Hb):
HA:
Hb:
I've tried to shoot this in the CaK band the last two weeks, but the continuum is very week compared to 1 month ago. I'll try again but with
2-3 hours of exposing....maybe the DA component with its accretion disk is inert/eclipsed or at a very low energy state?

Re: SU Lyn Call for observations by Katarzyna Drozd
Here is the recent (01Feb18) Cak region of SU Lyn's spectrum:
25X600sec exposures were processed through Isis to generate the very weak CaK continuum of SU Lyn. I've tentatively identified a NeIII line around 3868A.
(could be the Ti line around the same wavelength?)

Re: SU Lyn Call for observations by Katarzyna Drozd
First clear night of the year!
A spectrum of SU Lyn with eshel
H beta - [OIII] range, with a comparison with the M5III 13 Lyr, useful to highlight the emission lines [OIII] 4959 and 5007 appear clearly
H alpha range Ha in RV
James,
He I 7065 range : no line For line identification, you have to consider the emission spectrum as a all.
He I 7065 appears with He I 5876 (triplets) and also He I 6678.
No He I in emission in SU Lyn
[Ne III] 3869 makes sense (considering [OIII]). So the line at 3969 could be the other [Ne III] line.
PS: your -excellent- spectra are welcome for the database.

Re: SU Lyn Call for observations by Katarzyna Drozd
Thanks for the feedback and Nice results Francois!
Here are my SU Lyn spectra results shot in Ha, Hb, He5885/Na doublet, & CaK bands (2-5Feb2018):
Is the star M5III 13 Lyr in Miles/Edoline database or did you use it as your IRC star by shooting 13 Lyr just before dawn?
The line identification for NeIII for the CaK round 3866A is tentative I used Plotspectra's option and that NeIII line on the annotation list
looked like a match. I'll look for that other NeIII line you mentioned.
