Tabby's star (KIC 8462852) is dipping -- Urgent observations are requested


The mysterious  KIC 8462852 (Tabby's star) seems to be entering one of its rare dip, and observations are urgently needed to capture the event. The object is at V~11.88 and, according to Dr Tabby Boyajian, it has dropped by 2% (in r) so far. 

Coordinates (J2000):  RA 20 06 15.46 , Dec +44 27 24.8

We would like  time-series photometry with V filter, but all photometry is welcome. 

Thank you in advance for your attention to this target!

Best wishes - clear skies,

I just posted my nightly

I just posted my nightly observation in BVRI (transformed/aggregate of 2 obs) from last night - I don't see anything too alarming in comparison to two nights earlier or over the last month (same equipment).
