A fallstreak hole, also known as a hole punch cloud, punch hole cloud, skypunch, canal cloud or cloud hole, is a large circular or elliptical gap that can appear in cirrocumulus oraltocumulus clouds. Such holes are formed when the water temperature in the clouds is below freezing but the water has not frozen yet due to the lack of ice nucleation (see supercooled water). When ice crystals do form it will set off a domino effect, due to the Bergeron process, causing the water droplets around the crystals to evaporate: this leaves a large, often circular, hole in the cloud.

BLOGGER'S NOTE. It's a lie, you know. What they tell you in Wikipedia. I only included this bit of scientific babble for the one out of four of you (I mean the four who actually read this) who might be interested in HOW a big hole might form in the clouds, sometimes with a rainbow showing through.
They're weird, but no weirder than a lot of sky-effects like lenticular clouds (not shown here) that look exactly like flying saucers. Even these sky-holes set off storms of comments from YouTubers claiming they're chemtrails from jets (and actually, jetstreams sometimes play a part in the formation of these, but I won't get into that). Either that, or the Illuminati, because the Illuminati and the Freemasons are behind absolutely everything, including Isis (founded by Barack Obama!) and the Presidential bid by Donald Trump.
Don't believe any of it, it's Friday, nice out, and I'm going outside.
P. S. These gif slide-shows are relatively easy to make, but you have to get all your photos in the same ratio. They don't have to be the same size in pixels. If they aren't in the same ratio - these are 4 x 6 - you'll have white margins at the edges on some of them. Just sayin'. A display like this takes time to set up, but it has some advantages over just slapping up photos. Though I'm still trying to figure out what they are.
P. S. S. T.: These aren't made by all the meteorological forces listed in Wikipedia. God gets mad about what's going on in the world today, and stamps his foot. Sometimes I feel like doing the same thing.
