Mysterious Sunrise Over Argentina

This image is taken in Buenos Aires, Argentina by a photographer named Luis Argerich in October 10, 2011. This image draws too much attention and was featured in apod.nasa.gov — a website that features strange and fascinating images along with a brief explanation written by a professional astronomer.

Explanation: Why would a rising Sun look so strange? No one is yet sure. What is clear is that the above unusual sunrise was captured from Buenos Aires, Argentina. The body of water in the foreground is Rio de La Plata, considered by many to be the widest river in the world.

Although the above image is actually a combination of a normal and a very short exposure needed to avoid oversaturating the bright Sun, the photographer saw this unusual structure with his own eyes, indicating that this effect was caused by neither reflections nor distortions in the camera or lens.

Unusual atmospheric phenomena are frequently thrilling to see personally, and although most can be traced to well-known phenomena, others, for lack of more data, remain mysterious.
