A Strange Sunrise Over Argentina
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 last month 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. What looks like arms on this
monster illusion
might actually be, for example, low level clouds just thick enough to scatter sunlight without completely
blocking the Sun
. Additionally, the distortion visible on the lower part of the Sun's image might indicate a
Etruscan Vase
or
Fata Morgana
mirage possibly created by a curious
refracting layer of air
over the water. 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
.
