Unidentified Object on Mars

Found this Unidentified Object while searching Mars Photographs. This set of photos is from NASA Opportunity Navigation Camera SOL 115. Some other websites are reporting that there is wood in the photos. I noticed that the white glowing dot appears in three different photos with three different camera angles. Its as if whatever the camera was photographing was being blinded by a possible reflection or some sort of strange object. I zoomed in and it seemed even stranger because the reflection changes.
