@spacegeck I’ve never found the Bortle scale particularly useful. Might as well use mag/arcsec2.

A must-read letter by @travislongcore in LRT supporting the use of the term "artificial light".
"Our limitations here are not unrefined language, but the political will to understand and act, and those require plain talk."

@JohnBarentine after that, it's all a matter of matching the limits of the protected area to the municipal/county limits to implement outdoor lighting regulations or management plans

@JohnBarentine Having a "large" city like Sherbrooke inside the IDSR might seem weird at first, as it is not "dark", but the whole idea is to include the large sources of light to help reduce light pollution. Simply drawing limits around a dark area would have missed the point.

@JohnBarentine Interesting read, and glad you linked to the paper of light pollution reduction around Mont-Megantic. As I was reading your piece, I kept thinking about how this "lightshed" concept is very similar to how the Mont-Megantic IDSR (and the DarkSky Reserve concept) was built from the start.

@skyglowberlin @JohnBarentine yeah, I know that the use of light (both during and after the construction) is very different between Europe and the US, but even the size of the 2 sites for the factories are very different. reddit.com/r/dataisbeautiful/c

@skyglowberlin @JohnBarentine looking at this video posted 2 months ago, there seems to still be a lot of unshielded construction lightson generators used around the factory youtu.be/C5gMoN7cVvc?si=s80f7b (also visible in the screengrab from streetview.)

Most of the permanent lights fixtures seem to be shielded according to the drone view.

Yesterday, we marked the entry into force of new EU rules to empower consumers in the green transition.

Under those rules, companies will be forbidden to make vague environmental claims, such as stating that they are ‘green’ or ‘environmentally friendly’ if
they cannot demonstrate that they truly are.

Consumers will be getting better and more harmonised information on their legally guaranteed rights and on products’ durability and reparability.

Here's a recent study from a number of members of the same team, "Artificial light at night is a top predictor of bird migration stopover density": nature.com/articles/s41467-023

They find that skyglow is the second most positive predictor of birds migratory direction (elevation was the largest).

Forest and landcover had a much smaller impact than skyglow. #Eurodark

Later this year, we will add in the new data and make some improvements on the analysis of existing data that we published last year on data up to 2022: science.org/doi/10.1126/scienc

Lots has changed since then, especially in Europe... Is light pollution still increasing?

For the results to be reliable, we really need as many people from as many different countries as possible to take part. So please do share the news, and if you have a clear sky, please take part yourself!

The #GlobeAtNight campaign for March 2024 will run from March 1-10. We urgently need people from around the world to look for #Orion in the sky, and report back what it looks like here: globeatnight.org/

Please share with your networks, including off Mastodon!

#CitizenScience #LightPollution

Three maps of the constellation Orion with different levels of light pollution, with the question "What does Orion look like where you live?" and a link to the project.

I've made a website specifically for people in #Toronto / Greater Toronto Area with a couple of maps about the upcoming #SolarEclipse on April 8th. In short: If you're in Toronto and want to see the eclipse, then you'll need to travel.

hanno-rein.de/eclipse/

A map of Toronto which shows the path of the eclipse on April 8th 2024. The norther line of the total eclipse is just south of Toronto and the total eclipse is therefore not visible from Toronto.

@JohnBarentine I was a bit surprise with the phrase « DarkSky has certified more than 160,000 dark sky places across 22 nations, […] »

I had to watch the video to understand that they made a mistake with the total amount of km2 for certified places.

Just imagine reviewing 160,000 applications. No wonder you left that job 😜
