I was on my terrace at 5 in the evening and was clicking pictures of the cloud cover using my mobile camera.After taking 4-5 pictures and a short video when i viewed those pictures, their were 2 picture clicked within an interval of a min without turning on the camera flash. these images had a yellow color circular light which has decended down in the second image from it's innitial position in the first image. the other images that i have clicked after a minute with the camera flash does not show that yellow circular light. i am amazed and want to know what i have clicked .
