[vsnet-alert 3267] Re: Nova Aql 99 photometry

[Center for Backyard Astrophysics Brno station <cba@seznam.cz>]

Dear dr. Retter,

many thanx for your reaction. Of course we try to make as long as possible runs but you don't know what the weather do. Yesterdays run was stoped by clouds so we went for a sleep. I'll try to make another observation and mainly spent some time on better images analyzis than yesterday. (I made only poor reduction "to see").

Could you please tell us somethink about amplitudes of changes? Or - better - is there some URL with observations of this phenomenon.

With best regards
