Carlos Alberto and Germano Quast:
good and bad news:
we observe the stars during sometime,
from about 23:00TU to 00:30, when the sky
became hard cloudy.
In the begin it was surprisingly very clear.
The on line plot does not work very well.
It only works well in the "clear" filter, but
we could see also, with problems, in the B filter.
No obvious flare occurred when we were on each star.
Of course if we had so bad luck may be a flare ocurred
in the star we were not observing.
