No I talk like that normally

Nice! Altocumulus stratiformis undulatus, but with two intersecting systems of undulations. Think of them like cross waves at sea.

Oh, right. I figured that a person using a screen reader can probably see that one by themselves, but I suppose I could throw that one into the post body as well.

I had to do a double take when I first saw that "RASH" in the comment above. Is there a place where it's written like that instead of just SHRA or was that just a joke? Generally the pattern is always [intensity][descriptive attribute][phenomena], but the US system has so many deviations from the international standards that I can't be certain.

Thanks for the reminder!

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.
