[vsnet-alert 6184] V 2274 Cyg humping?

[Rudolf Novak <novak@hvezdarna.cz>]

Dear colleagues,

I obtained some time-series photometry on V 2274 Cygni (Nova Cygni 2001) 
which was observed with ST-7 here at Copernicus observatory. For first 
sight there is some modulation on the light curve which is visible on 
linear trend.

Because I do not have more data on the star, I welcomed message from 
Kamil Hornoch about his observations. I plotted those data and saw same 
waves on the curve.

Since amplitude is quite small and profile is very "sinusoidal" I'm not 
sure about that. Please have a look at Virtual Observatory 
(http://ada.astronomy.cz) where I uploaded the curve. Now I wait for 
Kamil permission to upload also his data.

With best regards
