This is cool, a group of researchers in #China combined maps of skyglow with maps of accessibility, in order to identify sites that would make sense as International Dark Sky Places certified by #DarkSkyInternational: https://www.sciencedirect.com/science/article/pii/S0169204624002068

@npub1uw8…88kr I hope at the FCC and not at the author?

Some good news from Zagreb - the sky has gotten darker during 2018-2022 🎉
Satellite data has a consistent small reduction in radiance.

@npub1dgz…p74y Suggests that in the "before" condition, the streetlights were responsible for half of the skyglow (now about 1/3 late at night). Do you know whether they are going to publish the results?

@npub17nc…9dam The link to the project is at the bottom of the last post. The presenter was Janette Siebert.

The Roadkill project sent professionally trained observers to make frequent observations in areas with high levels of reported roadkills by citizen scientists.
In the "high incidence route" (meaning frequently reported), an average of 2 roadkills were observed per night.
On the "low incidence route", 4 roadkills were observed per monitoring trip.
Shows the need for including population density information in analyzing #CitizenScience data.

Königswinter Germany reduced annual electricity consumption for street lighting from 1300 MWh to 385 MWh from 2017-2022, including turning off many streetlights during midnight to 5 am. The result was a savings to the city of 80,000€ per year.
The police of Bonn did a crime study, and found that there was no measurable change.

Anyone else who went to #ALAN2023 still have jetlag? You'd think I'd have trouble with mornings, but it's the afternoons that are somehow the hardest for me... 🥱
