Some people are already looking at this difference between overcast and clear on some species.
For example : www.sciencedirect.com/science/arti...

Here's the TESS-W data from the same moment. I had just installed the photometer over there on that day.

Similar effects could probably be detected from mountain tops, when there's fog over cities in the valley

🤣

I'm used to the usual effect of clouds (reflection of light pollution, darkening of the natural sky), but it's interesting to see the zenith being darker than "normal" once the sky overhead cleared but Montreal was still covered, and that the zenith became brighter once the sky cleared over Montreal

This reminds me of a very interesting observation a couple in 2022:
While taking SQC measurements from a park in Montreal's suburbs, I noticed that the zenith became darker just after the clouds cleared overhead but were still covering Montreal (2nd image). The clouds acted like a blanket over MTL

Not being able to attend #ALAN2025 this year, I was looking for someone there posting with the hashtag but didn’t find much :/

By the way, while these decorative street lights do have a prismatic lens, they are better than they might seem and emit ~120 lm of uplight (2.5%)

Don’t

Try a fresh one in Montreal next time

Using a LLM to generate this would fit into their agenda of using AI to run the government. That’s basically what DOGE is trying to do across the US government systems.

Here's map where you can see the light pollution and the locations of the different photometers (not all of them are on the graph).

Each line represent a different photometer. Some of them are located in very dark places with almost no light pollution, and some are closer to cities. This is why some get more dark than others during the eclipse.

What a fucking moron.

Don’t blame the « media ». I’ve seen many articles about this issue in the last year, and from many large media around the world. www.ft.com/content/29fd...

Ça montre à quel point ces gens ne sont qu’en opposition et ne cherchent qu’à contredire tout ce qu’ils voient.
