UFO Sighting in São Bernardo do Campo, São Paulo on May 25th 2015 – dark shape far in horizon … not to be seen with naked eyes .. only by cam

1 - I was taking some pictures of sunset, and I took a picture (Samsung S5 cam) and when I saw the results of pictures ... I had a surprise with an object which has appeared at that image (at only one pict); 2 - When I saw the pictures; 3 - For me, is clear an UFO; 4 - dark shape far in horizon ... not to be seen with naked eyes .. only by cam; 5 - I was very excited to see that image ... And also disappinted with myself for not to see with y only own eyes... 6 - As I understand, it was not possible to see with the naked eye, perhaps because my eyes do not capture certain types of light spectra but the phone's camera did it !!! Note: The Duration of this Event, as I understand, was the same time of the picture exposition (to take it) , maybe few seconds or less than this one .... P.S. I was signed the picture as Ayrton Knight (my nick name is "Knight") Thank you all
