Hello all,
Christian, Peter, Olivier and Stéphane, happy to see your results and the evolution of the nova since my last spectrum !!
What a pleasure to see these pictures of the OHP ... look forward to next year with many more spectros !!
With a less favorable weather than at OHP, I think, I have, I obtained the following spectrum of the nova Cas 2020 the 24th of August at 22 h 51 TU with my Alpy 600 (resolution of 501, JJ = 2459086.4521) and an acquisition time of 85 min :

- Nova Cas 2020 on August 5th, 6th, 7th, 15th and 17th and 24th, 2020 (identification of lines from PlotSpectra)
Like the Balmer lines, the FeII lines are increasingly visible !
Evolution of the Halpha line :
- Halpha line on August 5th, 6th, 7th, 15th, 17th and 24th, 2020

The relative intensity of the Halpha line is still increasing !
Evolution of the [OI] line :
- [OI] line on August 5th, 6th, 7th, 15th, 17th and 24th, 2020

But that of [OI] at 6300A seems to have changed little ...
Clear skies to all for the next steps of the evolution of the nova !
