UFO Sighting in Holbrook, Arizona on June 15th 2015 – taking cloud pics from car, quick burst, translucent

My wife was taking cool cloud pics while driving East on I-40, near Holbrook AZ (I think), saw this quick burst of light. Notice the small 'telephone pole' in one of the pics up in the light area. My wife took the pics, I was driving so she saw it much better, very quick, nothing after that. we had to keep driving.
