I was taking photos of a storm moving through the area, Southwest of Fort Worth, Texas and caught this image in one of the series. The photography is a hobby. I was using my IPhone 6. I researched meteorological optical phenomena, rings, circles, halos, compared pictures I found and did not find anything similar. 6:45 in the evening. The angle of the phone was probably 60-70*;SSE sky with sun beginning to set in the West and the moon is visible low in the photo. Thanks.
