UFO in Costa Rica

Scenery in Puriscal, Costa Rica
During the past several days I have been reviewing all of the photos taken since arriving in Costa Rica. I am organizing them and deleting ones that are similar. This is a big job, I have taken thousands of pictures, mostly to document changes on the property. On February 28, 2010 I took these two landscape shots of the neighbor's side of the valley. The time stamp on both images is the same, meaning they were taken one right after the other. The first photo looks normal.

On the second photo there is a bright spot in the sky on the left side. I almost deleted this one because it's similar to the first but something stopped me and I zoomed in on the bright spot.

This is what I saw. A very strange looking abnormality. I have never photographed anything like it.

  The design reminds me of the Sydney Opera House. What do you think?
