Re: GK Per Outburst
Nice results! Note: the period is very close to 2 days. Thus any comparison of the spectra should take in account the orbital phase. Currently ~ 0.25 and ~0.75 (Alvarez-Hernandez+ (2021, MNRAS, 507, 5805) Photometry: Flickering is high (truncated accretion disk + hot spot and accretion near the magn...

GK Per Outburst
The semi-polar [1] cataclysmic star GK per is detected in outburst (currently V ~ 11) Monitoring of the outburst is very welcome. Resolution : low and high Long time series is encouraged . The period is 2 days. 24 hours monitoring (Europe, North America) should be must. In that purpose, it is sugges...

Recalibrated UVES spectra
The UVES lib recalibrated.
I have not yet check in detail the new speectra.
I think its could be a very valuable ressource for amateur spectroscopy.

Re: KT Eridani (Nova Eri 2009) : new publication
Thank you for the input, Christophe 3 points: - the processus of publication can be very long - it was my second nova : http://www.astronomie-amateur.fr/feuilles/Spectroscopie/Novae/KT%20Eri%202009.html , just after Nova Sct 2009. I was very happy that I decided to buy a lhires after OHP Shelyak sta...

Improvments
Following same requests, Jaroslav updated the database. I did the following updates: • changed the default order of spectra on the website - they are sorted by JD, but the newest is on the top of the website; now, the users don't need to scroll to the bottom of the page if they are interested in the...
