[vsnet-alert 6213] V2274 Cygni humping

[Rudolf Novak <novak@hvezdarna.cz>]

Dear colleagues,

since it's not shining as bright as the story of the Queen of 
cataclysmics (my personal modification of VSNET name of WZ Sge :) I'd 
like to point again at V 2274 Cygni. The star is quite bright now and 
humping a lot. You can check the light curves at 
http://ada.astronomy.cz. I tried some simple period analyzing of last 
run obtained here at N. Copernicus Observatory and found period close to 
0.30d with amplitude slightly more than 0.1mag. I checked also 
comparison and found this modulation to be real one.

Personaly I think this is quite long period for superhumps and think 
about modulation caused by hot spot. Anyway more speak about that in 
VSNET lists should be very fruitfull to me to interpret those light changes.

Hope that after the conference in Germany we should have more people 
on-line to discuss :)

With best regards
