Full-on picture, Patrick!

Feels like being hypnotised! Not good to stare directly at it for too long, as you could get sore or tired eyes, even a chance of early blindness! Interesting how white light that we see is made up of rainbow colours when it is split by the air. The same think happens when the sun shines on the rain-drop particles of a rain storm and the air splits up the light into rainbow colours.

Feels like I am being hypnotised by the picture when I look at it! Not a good idea to stare at the sun too long, as it is too bright for our eyes and could cause early blindness and tiredness. Interesting how white light is split-up into rainbow colours when it hits the air. Same thing happens during a rain-storm, when the white light from the sun shines on the rain droplets and the light is split up into rainbow colours. From Rebecca Hill, Canberra, Australia

Thanks Rebecca. Coronas are my favorite optical phenomena to photograph. I am fortunate to live near the foothills of the Rocky Mountains where I see colorful corona frequently.

Most interesting picture, Patrick!

Don’t often see this particular cloud phenomenon seen from 35,000 feet up in a plane. Looking carefully at the photo, it almost looks like the sun is reflecting off of a thin layer of see-through icecap, through which one can see mid-level mackerel-sky patterned Altocumulus cloud, similar to pack-ice on a vast ocean below.

Thanks Rebecca. I fly a lot over the central US and this was the third time in the last 18 months that I was fortunate to spot a subsun and subsun sundog at altitude with a thin layer of cirrostratus at or just below the plane.
