[vsnet-alert 6282] WZ Sge: news from Bellatrix Observatory

Dear Colleagues,

Another observing session was successfully concluded on Aug. 13/14, under a marvelous sky.
I grabbed 1340 images in 6.25 hours and the resulting light curve is very good.

The light curve is, of course, very different from last night, with a fast raising to
maximum (in 0.01d) and slower fading (0.048d). The superhump profile is sometimes very
sharp, but it can have a secondary maximum just before to reach the minimum (sometimes the
profile is even more complex). Looking carefully, one can see how eclipses affect the
light curve during the rising, even if this is a very small effect. The modulation is now
of 0.2 mag.

The star faded during the run of about 0.04 mag, being 0.01 mag fainter than yesterday.

I performed PDM analysis on this dataset, adding it to my previous night data, getting a
probable period of 0.05728d.

You can enjoy the wonders of this star at:

Follow-up of this very promisong stage is extremely important.

Regards,
Gianluca
