2017-12-18 - Concord, NC - Sphere

Saw 3 large sphere shaped objects traveling towards 1 stationary object. They flew in the same trajectory about 45 to 60 seconds apart. It was cloudy and they were just under the cloud base. Were traveling at a slow rate of speed. There was an orange hue like a distant campfire. There was no color change just dimming and brightening. As each one passed they followed the same direction and made a slight angular turn of about 20 degrees to the south of my location. Each one was slightly closer as they passed over and I could see details of the third one. It appeared as if there was an orangeish haze coming off it but not enough to leave a trail. There was a smaller sphere inside of the large outer one and was positioned at about 7:00 area in the direction it was traveling. The smaller one illuminated the outer one. There was no structure to it, it looked like a giant bubble. There was absolutely no sound. The only odd effect was static electricity feeling in the air. The objects grouped to gather in a diamond shape and ascended into the clouds and that was the end of the sighting. I have an hd video that is about 6 minutes. As the last one went overhead my phone shutdown... I do however have the majority of it recorded with some detail of the closest one.
