Stranger Object Photographed.

I was doing some photographic work in the area of Folly Beach & the Morris Island Lighthouse.  It seemed like a typical day of shooting, the sun was shining, a slight breeze blowing etc.....  There was nothing really noteworthy about the day, until I reviewed the photographs later that evening.  My camera had been set in a rapid fire mode, which allows for continuous shots to be taken as long as the shutter release is depressed.  In one frame or photograph, a bright orange triangular object appears.  This object is seen in only one of the photographs of this sequence.  The shot just prior too & the shot that follows are void of the object, as are any of the other photographs from that day.  The three shots mentioned above where photographed from the same vantage point and all within less than a second of one another.  Times on the photographs are as follows (12:43:13, 12:43:13, 12:43:14).  I’ve been trying to wrap my head around what it is that I may have photographe! d.  I’ve shared the photos with only a few close family members and friends, but none of their suggestions or ideals seem to provide a logical explanation.  I would truly like to have an experts opinion on this matter.
