John,

Very good idea of observation! I really appreciate your spectra.
This star show a constant fascinating activity. It is also easy to observe.

Some ancient Deneb observations here:

It is really planed to run an intensive observation campaign next year on this subject.
(conserve your data (.dat or better, .fit) for a future archive).

Thanks for you appreciation Christian.
And your link has some very nice spectra of Deneb in it.

I will hold onto my spectra in fits format and look forward to taking part in the campaign next year.

cheers

John
