[vsnet-alert 10989] Re: QZ Vir superhumps update

[Josch Hambsch]

Hi,

I have been observing QZ Vir on Jan. 26.
Observing time from 01:41 UT (27.01.09) until 4:59 UT. I got two peaks 
during this time and the period calculated with PERANSO is 0.0607 d +/- 
0.0024 d.
The change in magnitude is about 0.15 mag.

Regards,

Josch
