A prominent 22-degree solar halo encircles the bright sun in a hazy sky over La Paz, Bolivia. The circular halo displays a full spectrum of colors, with the red band positioned closest to the sun and violet outermost. In the upper right quadrant, a modern skyscraper with a reflective glass facade angles into the frame, reflecting sunlight. A second, multi-story building with a light-colored, gridded exterior and numerous windows is partially visible in the lower right. Green tree foliage extends into the bottom-center of the frame, partially obscuring the lower arc of the halo. No individuals or discernible actions are present in the image.
