Recent V809 Cep observations
In Atel #5389, Munari et. al. reported "Nova Cephei 2013 has emerged from dust obscuration".
"The first positive detection of the nova occurred on Aug 17, after which the photometric observations were conducted also with the Asiago 67/92cm Schmidt telescope in addition to the ANS Collaboration telescopes. The last set of observations collected between Sep 4 and 7 allow measure the nova at average B=20.0, V=18.25, Rc=17.22, Ic=16.68. The red colors seem primarily a consequence of the large interstellar reddening affecting the nova. "
I checked V809 Cep with Light Curve Generator and noticed that V809 Cep already detected in June and V light curve looked like double line.
Is there any neighbor star that is difficult to resolve with V809 Cep?
Do we observe combined magnitude with any neighbor?
Or, does any other reason such as difference in filter transmission exist?
