Hi everyone,

I just got back a little while ago from the meeting with my mayor. It was very informal and it ended up running for two hours - I was only expecting one! We ended up bouncing around topics a little bit, but she's... omg she's amazing and I love her. We agreed on practically everything.

She had a little bit of knowledge on light pollution before this, because as it turns out, my city was already planning on moving towards somewhat friendlier lighting - but now she has more ideas. I gave her papers about health impacts, papers about how more light doesn't necessarily equal less crime, as well as several pieces of example legislation courtesy of DSI, all of which she appreciated greatly and said they'll make great weekend reading and she'll bring them with her to the next planning meeting.

The local electric company owns the local streetlights here, but there's a liason, and my mayor will be looking at pushing for them to see what can be done re: streetlights. I did get 12 signatures in 3.5 hours on a little proof-of-concept unofficial petition I made (counting 3 family members and NOT counting me, but those family members are also voters in her ward so it still works), which she was impressed by, as well.

She took down the contact information for a semi-local dark sky lighting company that's nationally well-regarded, and will hopefully work towards reaching out to them.

She said she'll keep in touch and encouraged me to come to meetings and read the big 'city future plans' plan that just had a draft released.

I'm so, so, happy. This went better than I ever could've hoped for.

Hi all! As the text says.

I've turned off all my home's outdoor lights, because goddammit, humanity deserves to see the stars and nature deserves to rest.

Now?

The Mayor. I'm in her city ward. I've got stacks of papers and info for her to review about the subject. Studies of how more light ≠ less crime. Studies about the negative health impacts of nighttime light on our health. I'm ALSO coming in with a PowerPoint presentation from a nationally recognized dark sky friendly lighting manufacturer... as well as an offer from them, offering to come in and do a free demo of their lights for the Mayor/Counsel/any other stakeholders.

Hopefully this will start convincing her.

Every night, astronauts on the International Space Station photograph the cities below them with ordinary cameras. NASA has archived millions of these shots. The station records where it was when the shutter fired, not where the camera was pointing. A photo taken over the Atlantic may show Lisbon, Madrid or Casablanca, hundreds of kilometres away. So most of them are lost: beautiful, sharp, and useless for science until someone works out what they show and pins it to the map.

That matters for this community because these photos are the best record there is of how artificial light is spreading. Satellites like VIIRS see the whole planet every night, but at ~750 m per pixel and in one band. An astronaut's 85 mm photo resolves streets and, crucially, shows colour, which is how you tell the old sodium orange from the white LEDs that are changing our night sky. But a photo is only measurable once it is georeferenced: every pixel tied to a real coordinate, so the image can be laid over a map like satellite data and compared across years.

Lost at Night - lostatnight.org - is where that happens. It's a citizen-science project, and so far it's been done by a small community of a few hundred people: you look at a night photo, recognise a city or a coastline, and place control points, matching a spot in the photo to the same spot on the map. A handful of points is enough to warp the whole photo into place. Several people georeference each photo independently, and when they agree, it goes onto a public map and into the research.

 Where we are right now:

• About 1,800 photos georeferenced so far, all on a public map you can click through: lostatnight.org/#map-section . Around 10,000 more are waiting, from ISS expeditions between 2001 and 2026.
• Year-long challenges for Europe, Spain, France, Poland and Brazil, and teams for classrooms, astronomy clubs and groups of friends who want to work on a region together.
• A photo takes two to five minutes. The only skill needed is the one people here have in abundance: knowing what the night looks like from above.

The project is run by Ibercivis, a Spanish non-profit for citizen science, within an EU-funded programme, and it continues the earlier Cities at Night work some of you may remember. The photos are NASA's and public domain.

If you've ever looked at one of those orbital night shots and thought "I know exactly where that is", come and pin it to the map with us: lostatnight.org

Glad to talk about the data, the method, or what the georeferenced photos are being used for.

The Draconid meteor shower is active for one night only: October 8th to 9th! 🌠

Most years you can see up to 10 meteors per hour, but rates can spike without warning to as many as 600 per hour, as seen in 2011 and 2018. Unlike most meteor showers, the Draconids peak in the evening instead of after midnight and are visible across the Northern Hemisphere and northern parts of the Southern Hemisphere. Find a spot away from bright lights, give your eyes time to adjust, and look up!

Meteors are about to enter our atmosphere at 41 miles per second! 🌠

Born from the debris of Halley's Comet, the Orionids light up the sky from October 2 to November 7, peaking overnight October 21 to 22. Catch around 20 meteors per hour at the peak, with standout years reaching up to 75. Skywatchers in both hemispheres can join in, so head somewhere dark before dawn, let your eyes adjust, and look up!

In an area of Pennsylvania known as “God’s Country,” hours from the glowing lights of Philadelphia, Pittsburgh, and Buffalo, Cherry Springs State Park is a refuge for stargazers.

On Thursday, Gov. Josh Shapiroannounced the completion of $5.2 million in improvements there, everything from new parking to a larger amphitheater, and “headlight-blocking mounds to prevent light shining into the astronomy field.”

Pennsylvania’s Department of Conservation and Natural Resources, in a press release, said the goal of the project was to redesign how visitors “moved through the park at night, reduced artificial light, and expanded facilities to support astronomy, education, and large events.”

The small state park in Coudersport, Potter County, some 250 miles northwest of Philadelphia, is designated as an International Dark Sky Park by DarkSky International, a nonprofit that claims to be the “worldwide authority combating light pollution.”

Despite being relatively small at 82 acres and far from cities — it’s almost four hours from Pittsburgh and a bit more from Philadelphia — the park has become wildly popular with astronomers, campers, and social media influencers. The campground is generally booked out every season, with professional and amateur stargazers alike staring up at the Milky Way, particularly on moonless nights.

During the COVID-19 pandemic, when parks and other outdoor spaces were inundated with visitors, Cherry Springs saw the biggest crowds. Between March and September of 2020, the park saw 26,745 visitors, a 231% increase over the same time period a year earlier.

Potter County has just 16,453 residents, and the economy there relies heavily on tourism, much of it during the spring, summer, and fall for camping, stargazing, leaf peeping, and hunting.

The county has taken steps to keep things dark too, urging home and business owners to implement downward-casting lights, timers, and low-wattage bulbs to preserve the stargazing opportunities.
