A re-edit of an image from 2012, taken at the north Narrabeen rock shelf on the northern beaches of Sydney. A lone photographer capturing the grey sunrise adds scale to the scene.

This is about the highest point in Allegan County, Michigan. The low clouds have a great view of the growing soy beans.
The clouds just took my attention and I am really glad that that came across on the photo.
I was also happy to see that we had good sky conditions for the ODC for yesterday. Lucky me. :) Well sort of close to the magic hour...

Nacreous are one of the most beautiful of all cloud formations, but they are also the most destructive to our atmosphere. Their presence encourages the chemical reactions that break down the ozone layer, which acts as an essential shield protecting us from the most harmful of the sun's rays.
Also known as "mother-of-pearl clouds", nacreous clouds exhibit spectacular iridescent pastel colours, caused by the sunlight diffracting as it passes around their tiny ice crystals.
Since they form much higher than common clouds - at altitudes of between 12 and 15 miles - nacreous clouds are most apparent around sunrise and sunset when their colours stand out against the darkened sky. The stratosphere is extremely dry, compared with the cloud-filled lower atmosphere, so the air needs to be very cold indeed for any ice crystals to be able to form there.
Nacreous clouds only appear when stratospheric temperatures are below -83C.
Well if you are from Europe, then they are not that unusual, but in may and in the middle of the desert of Saudi Arabia, they are quite rare. They provided a decent cover during my trip from Taif to Riyadh, which is approximately 800kms. This was taken midday.
