Bright object appears on Northern exposure, Bradenton, Florida

Bright object assended into view on Northern exposure of house.  Object appeared to be self-illuminating, able to hover and made erratic movements until quickly receeding to the Northeast, as an airplane appeared from that general direction (North/ North-east).  While hovering, object made no perceivable sound.  The object's movement's appeared erractic regarding flight course; despite this, its rapid movement in different directions appeared intelligent/ proactive, rather than reactive or a natural phenomenon.  The other witness stated that the object appeared "spherical" in shape, I could not recognize a constant shape to the object, which in my perception only appeared to be in constant fluctuation, regarding both shape and movement.  Airplanes and helicoptors frequent this airspace and are easily recognisable, this was neither.  Vague cell phone video taken, hardly discernable light present for mere seconds.
