Strong Sun Corona


This impressive display was first noticed when I walked past the pond. Normally there is enough variation in the size of cloud droplets for their diffraction patterns to overlap producing a white background.

The rings are here are unusually well defined so the water droplets must have been a very even size.

Great care is needed when trying to take this kind of photograph. Always ensure that the camera is in the shade of the occulting disc. An assistant can be a great help here.


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