Looks to me like flares of some sort... maybe attached to one of those model rockets with the little parachute? About a year ago, they busted some guy trying to recreate the “Phoenix Lights” by launching helium balloons at night with flares attached. Unfortunately for him, his neighbor watched the whole thing.
