Blue spherical-shaped UFO over Greenville, SC

On January 1st, 2015, a person was in Greenville (South Carolina). He took pictures chemtrails in the sky. Later, he noticed a strange and impressive blue spherical-shaped UFO! What is it?

Witness statement:

I was taking photos of chemtrails.. When I looked at the photos I saw this object in the photos. I went back outside and could see the object with my naked eye. I took more pics and enhanced them. In one of the photos, it appears to be behind the chemtrail. I had two of the photos enhanced. You can see the lights, they appear to be in a pattern.

I tried to get video but was too shaky to get a good video. I have never seen anything like this in my life. A little shaken up! After trying to get video, it disappeared.
