Thanks! Time really is the most important ingredient. Look at enough sunsets and sunrises with an adequate camera on hand, and every now and then a great scene will come up. After that it's just point and shoot.

Thanks! Yes, it is a photo. The moth was chilling on a window after sunset. The blue dots are out of focus apron lights.

They sure don't tend to do that, but there are still mundane explanations for this. An unintentional collision between the satellite and another object being one of them.
"I find it hard to believe they would use such a big satellite as an ASAT target," McDowell said.

Not because of Kessler syndrome, just your run of the mill space debris reentering the atmosphere and increasing the amounts of certain metals up there that contribute to ozone depletion. In other words, that may well happen even if we're lucky and avoid Kessler syndrome.

This one turned out a bit more blurry, but the aurora itself is too good not to post here.
These guys danced accross the sky, reaching quite far into the southern sky as well. Picture taken on 4.4.. I'm just mad that while I had hauled my tripod with me, I had left the camera mount back home :))). I stuck a bench into the snow and steadied my hand against that. A couple of these turned out surprisingly well.
Cirrus and Cirrostratus progressively invading the sky are a telltale sign of an approaching warm front. In this case it was an occluded front that was rolling in. It snowed that night.
Don't be decieved by the anvil like shape, heavy looking precipitation and icy look of this cloud! This is far from the size and power of an actual Cumulonimbus. But it is interesting in that it fits every criteria of a Cumulonimbus capillatus incus, except the bit about considerable vertical extent for the genus. I'm quite sure that this guy didn't raise its head much above 2 km AGL. I suppose it could be classified as a Cumulus of some sort, but it really doesn't fit well under any genus. Our systems of classification are just something that we made up. Clouds are under no obligation to conform to them. The same is true for everything else in the universe as well.

Almost forgot to get back to you about that last part: Yes it did, but this wasn't that.
Here's a picture I took when the smoke was making a sunset unusually red:

This was a telephoto at the horizon at around midnight. The sun was only a bit above the horizon, so the lighting was similar to a sunset/sunrise.
Here's another picture of that same midnight, looking towards the sun.

Nah winters are beautiful up north. Sometimes also in the south, but only rarely around the southern coast.
Picture taken in August 2022. [Fluctus](https://cloudatlas.wmo.int/en/clouds-supplementary-features-fluctus.html), also known as Kelvin-Helmholtz wave clouds, form when wind shear causes instability in the (usually the upper) surface of a cloud. The formation is short lived and relatively rare. It can also only be seen well from the side like here. [This video](https://youtu.be/qgamfo86FQo?si=_XStP990M2Rtm_ec) contains a good explanation of the physics involved here.
Taken last summer from Riisitunturi, Posio, Finland.
Picture taken at 01:30 on 5.7.2023 at EFHK.
Some of the Cc is of the variety undulatus. Miscellaneous Cirrus in the lower part of the image.
Picture taken on 25.6.2023 at 01:27 local time. A sun pillar is formed when horizontally floating hexagonal ice crystals (in this case within the Cirrus) reflect light. Kinda like the reflection of the setting sun over wavy water, but in this case upside down.

Thanks for notifying. Should be fixed now.

I volunteer. I modded a similar subreddit back in the day before leaving Reddit, and am fully fluent in latin cloud nomenclature.

The notations can be confusing, especially around noon and midnight. Is midnight am or pm when it's equally distant to both the previous and the next noon? Why does 12am not follow 11am???
Where I live we use 12hr time in casual spoken language but pretty much always specify the time of day as well, like eight in the evening or twelve at midnight. But for anything written or even remotely formal, 24h time is used for obvious reasons.

Sure, but the vast majority of people live in low lying areas and even then it doesn't shift that drastically. You need to climb a mountain to see the difference when it comes to applications of daily life.
Although now that I think about it. The same criticism applies to pretty much every definition of temperature that is based on the behaviour of matter. This also applies to Kelvin. Temperature is a property of matter and every type of matter behaves differently.

The thing to remember is that air is a great insulator. Air at 100°C isn't nearly as bad as say water or metal at the same temperature against the skin. In fact, the air that comes in contact with the comparatively cold human skin will cool down rapidly, forming a layer of cooler air around you and lessening the sensation of heat further.

100°C is nice. And what's a steaming session? Throwing water onto the rocks for steam every now and then is just standard operating procedure.

Water is everywhere.
Cooking, weather, etc. You are also water.
