Pulsating circle, very bright took an erratic turn and disappeared in a bright flash.

Looking east towards Gold mtn east, south east a bright perfectly circle shaped project appeared in the sky. Far far brighter than an other passing planes and would pulsate very bright to black. We saw this two times before audibly confirming with one another what we saw, it faded out a third time while appearing to veer off in another direction disappearing in a flash of light. We had been watching the meteor shower and whatever object we saw moved in an unnatural way, nothing like meteors we have seen previously.
