In the past month, I've captured three things in the sky that were unusual.

A horseshoe vortex:

and a couple of clouds or contrails that were out of the ordinary:

Feel free to add your unusual things in the sky.

I didn't figure out what caused this (Superman?), but it was a large area affected (the pics were taken 10 mins apart while driving on streets).
Note the ripples in the first picture.

The two last pictures do look suspiciously like the trail of a secret military plane of sorts, or a UFO as suggested.

Holy synchronicity, Barry! Because of the unusual things I have been photographing in the sky this month, I ordered three books about clouds just a few days ago.

Just last evening, the first arrived. It's called The Cloud Collector's Handbook, and it is written by Gavin Pretor-Pinney, founder of the Cloud Appreciation Society.

According to page 78 of the handbook, what you have there is a distrail, short for dissipation trail, which is formed when "a plane cuts out a gap as it flies through a cloud layer. This happens when the heat and turbulence of its engine make the cloud droplets evaporate, or when it introduces icing nuclei that encourage the cloud's supercooled droplets to freeze and fall below." As near as I can tell, a distrail is kind of like the "negative" of a contrail. Perfect for a photography forum, no?

In any event, way cool!

Cheers, Jock

the near far nord, eh!
I've been in the habit of "collecting" clouds lately for a project that is brewing inside my head. There are soooo many different formations that we take for granted... until we open up our eyes... and our shutters!

Jack Borden, of For Spacious Skies says the sky is "the greatest show off earth."

Might I humbly suggest that we turn this thread into kind of "a project"?

Cheers, Jock

I actually remember seeing a missile test in southern California, probably in the early 2000's, that looked a lot like this (less bright of course, more phosphorescent white and far off in the evening sky). You could actually see the flight of the missile and the intercept missile that struck it. It was surreal (and a little scary). Wish I'd have gotten some photos.

Also known as 'cloud canals', and made in the same way as 'fallstreak holes'.

I don't know what that is . . . do you? And where was it taken?

Edit for additional: following the link that bredman posted above, that might be a Fallstreak hole.

HI Jock

It was actually taken just outside my house... I was out trying to get my lawn cut before starting the BBQ... looked and the sky just got weird... so the BBQ was a little late while I was trying to get a few shots of the clouds in before they disappeared... and they certainly didn't last too long!
