Atmospheric Optical Phenomena

Solar halo.

The Halo is quite large: its diameter is 44°. One need at least a 20mm lens on FX format.

The presence of ice crystals in the atmosphere makes it visible and it's fairly easy to spot.

A veiled sky or cirrus clouds in the sky is the typical scenario.

 

Update: What looked like a sun pillar must be some in-camera reflection: changing lens is still there but eventually I've taken some shot rotating the camera and the "light beam" from the sun rotates too.

Earth Shadow: Sequence.

 

The sun below the horizon project the shadow of our planet into the atmosphere.

I thought it was interesting to show because it might be a not so obvious atmospheric phenomenon.

Pretty colors.  

 

Thanks for sharing.

I've shot the sun halo several years ago, but without the sun pillar.  The halo was not as large as what you captured and a 40mm equivalent covered the entire halo.

 

I've never know the earth shadow phenomenon.  Thanks for the input.  Did you crop the top and the bottom of the single frames?

[Marco Lanciani]

Akira, thanks.

I only cropped the bottom. You can see the full width.

 

You know, this is still a fisheye so the horizon must be centred to keep it straight.

Akira, I was wrong. Actually I've cropped also the top, but just a little. So little that I was sure I used only the top half of the image... which was also my original intension, and I kept the idea.

Sorry.   

[Akira]

Marco, no worries.  Thanks for the details anyway!
