Tabby's Star - KIC 8462852 - remains one of the more interesting and mysterious objects in the sky.
There is a good update at "Updates on Boyajian’s Star" - Astrowright's blog and "Bradley Schaefer: Further Thoughts on the Dimming of KIC 8462852" at Centauri Dreams has the latest on the controversy over whether the star has undergone long term fading.
Ultimately to resolve this more data is needed.
There is a Kickstarter Project - "The most mysterious star in the Galaxy" - to get serious time on Las Cumbres Observatory, the request is almost 2/3 of the way there with a few days to go.
Kick in if you can!
