[vsnet-alert 6137] WZ Sge: evident changes in the light curve

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

Dear Colleagues,
the final result of my third run looks very interesting. 

The light curve clearly shows the main features previously recorded. The amplitude of the
main modulation is a bit smaller (0.4 mag) and there is a quite large (in time) first
secondary maximum, while the other ones are sharper, with the exception of the last one,
with a very particular shape.  So, the secondary peaks seem to confirm that they can be of
two  types (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; see above); the third ecplise shows a
similar profile too. The main maxima have now a more regular aspect, as the previous day
their shape was both sharp or a bit broader, while now they are all quite sharp and
well-defined.  It seems like the star has undergone an evident change in its behaviour. By
the way: the star looks about 0.2 mag fainter than yesterday. The small noise in the third
peak is dued to some clouds.
