We just need to learn to call it Boyajian's star; I agree with footnote 2.

Just doing a mini-paper on the Kardashev scale, calculating the levels 
from fundamental physical constants. Very entertaining if you like 
dimensionless numbers to weird fractional powers (a K2 civilization has 
a power between (c^5/G) alpha_G^1/2 alpha^5/2 beta^1/4 and  (c^5/G) 
alpha_G^1/2 alpha^-2 beta^-2 - anybody recognize what the c^5/G term is?).
