Astronomers Explain Mystery Star?s Unusual Behavior
So no new strange sunspot behavior. ah well.....
What's going on in that system is rather interesting, though. No alien technologies? Oh well. The system itself is quite full of enough amazing events as it is.

It's gerbils. They're tired of running the little gerbil generators that keep the lights on. Someone needs to look in on them!
I can't imagine any way in which we'd be able to pick up any signals... even if they're there.
It would take an unimaginably large amount of power to come from an omnidirectional source for us to detect it.... and I doubt E.T is beaming signals directly at us.
Is it possible that the light curve dips we see with Tabby's star are not actually dips in its brightness at all, but instead are caused by two star systems almost perfectly aligned with each other as our perspective views them?
Imagine there was another star system behind Tabby's star.. perhaps even a binary system with Tabby's star being in the foreground and two more stars orbiting each other some distance behind Tabby's star..
As the background stars orbited each other, their orbits may cause one of them to be partially visible most of the time.. Only when the two background stars align themselves with our line of site through Tabby's star, do they become completely hidden, thus appearing to reduce the light coming from Tabby's star.
The 100 year dimming trend could be caused by the relative motion between Tabby's star and the background object(s) as seen from Earth's perspective.
Or am I full of horse manure?
If this were the case the big dips should be regular. They aren't. If it were a partially complete Dyson sphere the dips should occur regularly too. They don't. Anything involving orbital motions should have a more definite period than what is observed.
