Eclipse Iridescence - When you have planned an eclipse viewing for years and traveled thousands of miles, an accompaniment of sky optical effects is not wholly welcome.

Robert Goren took these shots from south of Tahiti during the partial phase of last Sunday's total eclipse.

The thin clouds are suffused with iridescent colours as their small droplets diffract the light of the crescent sun.

Green sun?   The 'real' sun is somewhere in the bright overexposed region. This is one time when a lens reflection is really useful to show the sun's shape. ©Robert Goren, shown with permission.
