[Aavso-photometry] Var Vul 05 - refined superhump period

[Tonny Vanmunster]

Dear colleagues,

Following my detection of superhumps in Var Vul 05, and the confirmation by
Brian Martin (CBA Alberta, Canada), I managed another unfiltered CCD session
on Aug 27/28, 2005. I again used a 0.35-m f/6.3 telescope with unfiltered
ST-7XME camera. This time, the session lasted for 3.1 hours (till clouds
made further photometry impossible). The variable had faded to about mag
17.8, but still showed superhumps with an amplitude of about 0.2 mag.
Combined with my observations of Aug 23/24, 2005, I find a refined superhump
period of 0.0590 +/- 0.0002d (ANOVA).

The lightcurve and further information is presented on my website

Best regards,
Tonny
