Red and white pulsating motionless orb emitted a single bright sparking flash remained for a few minutes then disappears.

A bright red light that faded and change to white intensified then faded and change to red slowly changing back and forth every second or so, predominantly red.  It was as bright as a radio tower light but was high in the sky and motionless and in a spot that I know no such tower could exist.  There was a spark of white light to the right of it that lit and faded away as the red orb continued to pulse motionless.  After about 3 minutes it faded motionless from site.
