Hi all,

great spectra! Joan, your profiles are *top level*!

Significant changes of neutral oxygen line in two days:



Have a nice observations!

Hi all, my contribution with some profiles, from H-alpha to NIR regions. Some clouds in the sky. http://quasar.teoth.it/html/spectra/rsoph_20210809_844_PB.png http://quasar.teoth.it/html/spectra/rsoph_20210809_885_PB.png http://quasar.teoth.it/html/spectra/rsoph_20210809_903_PB.png Interesting, the ...

Hi all, great spectra! My contribution with some observations in near-IR interval, using Lhires III with 830 l/mm NIR blazed grating. The different evolution of neutral oxygen lines, O I 7772 and O I 8446, from june 13 to June 16 (Lyman-beta pumping?) http://quasar.teoth.it/html/spectra/novaher2021_...

Hi all,

new spectra for March 26.





A couple of cloudy nights are expected here... Hope it's better for you!

Hi all,

I tried to observe the nova with a very strong atmospheric turbulence, especially for the second spectrum. Near-IR regions.





Clear sky!

Hi all, the nova has gained brightness (about one magnitude) compared to the mag 16 minimum that occurred in mid-February. Christophe, very nice profiles! You were around minimum in February spectra (very faint target!). Yesterday observation, mid-res as usual. The h-alpha line profile changed a lot...

Great spectrum Woody! I saw it on ARAS db. It's very interesting to see so many features beside h-alpha line. Strange that you can't see my pictures. This is the first time somebody says that to me. I can reach them on ARAS forum with Safari for IOS or MS Edge on Win10. I'll e-mail you... So, you're...

The feature appear clear also in recent low-res spectra in DB (Woody, Jean-Michel). The updated stacked chart. http://quasar.teoth.it/html/spectra/novaper2020_series2.png It seems that blue peak has decreases but without a "solid" continuum (lacking in my last spectra) I think it's difficu...

Hi all!

Tonight (noisy) spectrum



H-alpha emission line is constantly evolving. As seen in the 8 march profile by Etienne (database), red peak has become higher than blue peak.

Outstanding work, congratulations François, Jaroslav!

ARAS community is growing and enhancing the sharing tools, I'm happy to be in this team (with my little contribution, nothing compared to that of the "largest shareholder" Joan )!

A warm thank you!

Paolo
