[vsnet-alert 6136] WZ Sge: lightcurve evolution and additinal details

[Gianluca Masi <gianmasi@fr.flashnet.it>]

Dear Colleagues,
On July 25/26 I've got other useful data, right now under reduction. I've just finished
about 30 percent of the whole data set and the light curve easily shows the main features
previously recorded. 

The amplitude of the main modulation is a bit smaller (0.4 mag) and there is a bit large
(in time) first secondary maximum, while the second one, just at the end of this sub-run,
is sharper. So, the secondary peaks seems to confirm that they can be of two types
(details on my website, but confirmation is needed): sharp or broad. Looking at the second
eclipse, it has a different shape, broader then the first one, but also yesterday I
discussed a particular eclipse looking flatter than the others (a zoom is now on my
website). The data under reduction will permit to better conclude about the current status
of this star. BTW: the object is about 0.2 mag fainter than yesterday.

The partial, new lightcurve, with some additional material, is at:
