((NUFORC Note: Please see comment below from a reader of this report. The light may have been part of a sprinkler system, according to that individual. We cannot confirm that fact. PD))Brilliant electric blue pulsating light moving at an incredible speed soundlessly passing within 100 yards of our vehicle.My wife and I were driving north on an isolated section of State Highway 79 when we observed an object which at first appeared to be a police car with flashing lights. It appeared to be stationary in the center of the road approximately a mile ahead. As we closed the distance to approximately one-half mile, the flashing lights appeared to move slowly forward and then to the left approximately 75 to 100 yards. When we were approximately an eighth of a mile from the lights, we recognized that the lights were hovering approximately 10 to 20 feet above the ground over the field west of the highway. To our amazement as we watched, the lights suddenly sped at an incredible speed directly south passing our vehicle on the left side. In less than a second it seemed to stop and hover in the field approximately a half-mile behind our vehicle and remained there until we drove out of sight.The light appeared to be an brilliant electric blue pulsating pattern, approximately 18" to 24" in diameter. The center appeared to be circular with many narrow shafts of light emanating from the circle forming a criss-cross pattern. It moved at an unbelievable speed yet made no detectable sound.((NUFORC Note: We spoke with one of the witnesses to this event, and we felt she was unusually credible. Neither she nor her husband had ever seen such an object before. NOTE: Not included in this report is that they attempted to dial the local police department, using their cellular phone, and it would not function. Minutes later, after the object had left the area, the phone reportedly once again functioned normally. PD))((FOLLOW-UP MESSAGE FROM A READER))in ref to the below sighting, I know exactly what this was as I live in the area. In that stretch of the highway there are several sod farms that use pivot sprinklers. At the end of the sprinkler set is a blue strobe light that moves with the sprinker, this let's the farmer know where the sprinker is and that the sprinker is operating. Infacts as I look out my window now, I can see a blue light, red light and a white light, all coming from the irrigation sprinkers. Furthermore, there is no cell phone coverage in that stretch of highwaythanks!((END FOLLOW-UP
