Pulsating bright white and blue light darting in different directions and specific patterns.

Observed object similar to a star but much brighter. Pulsating smaller blue light.  During hours of observation the object traveled for short distances on the diagonal, back and forth, up and down and backwards and forwards.  It also made a flourish, much like an "8," sideways, but not joined up.  It actually made a perfect square as well!  
Two airplanes came by and each time, the object remained still until the plane was out of proximity.
It actually was so bright that it formed an aura around itself, and I could see l clouds pass by.
It should be noted that it has been there every subsequent night up until last night, August 15th!  It is positioned toward the tail end of the handle of the Big Dipper, to the south of it. Each night it has been at the same co-ordinates.
We observe that the description is not inconsistent with a regular sighting of the star, Arcturus, seen over several nights.  PD
