Iridescent Cloud

Iridescence just outside the corona Iridescence and fine cloud structure

Cloud just outside the corona shows strong iridescence with metallic hues close to the sun shield. Even with the area round the sun blocked out eye protection was still necessary.

Fine structure in the cloud gives a very complex pattern of colours.

Iridescencent cloud and a distrail Pastel hued iridescence

A good 20 degrees from the sun and the iridescence was not as strong, but the colour differences were still quite distinct. A distrail cuts into the cloud at at lower right.

The iridescence is visible as green and purple patches within the recently formed cloud. The pastel hues here are typical of iridescence far from the sun.

Never look directly at the sun !   Shield the sun and use proper eye protection against the glare.
