Hi All,
Hopefully Meteoblue was right tonight, showing only a two hours clear sky over Pyrénées Mountains. The time to take a spectrum of this Nova, without filter :
- Nova Per2020 Rspec 13 dec 2020 Fred Pastor.jpg (47.66 KiB) Viewed 6743 times
Intensity of the Halpha remain strong with an intensity at 15.50.
Cheers

A cette occasion la Nova Per 2020 était un bon test.

A spectrum taken the Dec. 13, by using a very small refractor, a Takahashi FS60 (60 mm diameter) and the Sol'EX spectrograph (1200 lines/mm grating + 10 microns slit) + 4 x 900 seconds exposure:
The resolution is R=3200 by using the these configuration (not optimal, the very first light on star of a spectrograph optimized for solar observation ->

Hello ,
After days of bad weather, I have observed the Nova last night, that is the result.
Greetings, J. Guarro.

Hello all,
Finally a clear sky for several days...The following spectrum of the Nova Per 2020 was obtained last night the 15th of December at 20 h 12 TU with my Alpy 600 (resolution of 533, JJ = 2459199.3419) and an acquisition time of 65 min :
- Nova Per 2020 on December 15th, 2020

- Nova Per 2020 on December 6th and 15th, 2020 (zoom).
The relative intensity of the [OI] line at 6300A seems to increase and the red part of the spectrum seems also to evolve.
Clear skies,
Christophe BOUSSIN

Placez une comparaison du jour 16-12-2020 avec les jours 14 et 15 12-2020. La variation de l'OI et du CaII est significative. Les profils ont été obtenus en interposant un filtre rouge.

Hello,
You can see two spectra comparison in the near infrared.
Cheers, J. Guarro.
