Observatoire de la belle étoile: VV Cep

[Olivier Thizy]

Hello,


I think I'll try a full nigh run on VV Cep to see what kind of small timescale variation exist...

I'll try 7 Cep as reference star for my instrumental response.


Cordialement,
Olivier Thizy

66 spectra so far, covering a 5h period (acquisitions are still going on but clouds are coming my way and I lost already about 30% of the signal...).

Here is the full spectrum (18304 sec exposure!):
