Red/orange object - circle to chevron shape with lights hovering overhead with no soundReddish-orange circular object seen hovering in sky over the San Tan Mountains. Object moved closer in the sky, and appeared to be a chevron shape with red lights. Hovered over head and made no sound at all. I took a photo of the original red object and strange gray shape is seen to the right of the object as well. As object came closer and lower in the sky, a second red light appeared in the sky directly behind and to the right of original object. Original red object was hovering directly over my aunt and I...we were on horseback so it was difficult to keep looking without straining my neck. I was treating her to a birthday sunset ride and she said that my uncle would be watching the sunset and surely taking photos so we stopped watching and rode off. My family back at the barn noticed nothing but we're facing a different area of the sky.My aunt is a retired ((deleted)) manager now living in North Carolina. I am a licensed ((deleted)) in Gilbert, Arizona. I ride horses in this area often. On October 25, 2016, at 18:35 I saw a line of moving lights in this exact area of the sky.
