Up until now, the interstellar comet had been brightening as expected. But now, the observations from mid-September 2025 are beginning to rise above the upward-sloping line of brightening that would have been typical for a comet nearing the sun.
(There has been a lot of talk that 3I/ATLAS might be an interstellar probe due to its great speed & a trajectory that takes it close to Jupiter, Mars & Earth before it slingshots away using the Sun’s gravitation.)
A team of scientists, led by Xabier Pérez-Couto of the University of A Coruña in Spain, has traced the path of interstellar object 3I/ATLAS back 10 million years. Indeed, this is only the 3rd-known object found traveling in our solar system that didn’t originate with our sun and its planets. Its trajectory tells us it must have come from another star system, but which one?
They traced the path back over 100 million astronomical units (9.3 quadrillion miles) but couldn’t find where it started towards Sol. You can read on for lots more!

One of the reasons why most locations on Earth do not enjoy exactly 12 hours of daytime and 12 hours of nighttime on the equinoxes is how sunrise and sunset are defined. If sunrise and sunset were defined as the moment the geometric center of the Sun passes the horizon, then the day and night would be exactly 12 hours long. But that is not the case. Sunrise and Sunset are defined as the exact moment the upper edge of the Sun’s disk touches the eastern and the western horizon, respectively. The time it takes for the Sun to fully set, which can be several minutes, makes the day just a bit longer than the night on the equinoxes.
The day with the same sunrise & sunset time is September 25th. The sun still does rise directly in the east & set directly in the west, so don’t forget to pack your sunglasses – a lot of our roads are laid out east/west making the sunrise and sunset around the equinox sun a positively blinding proposition!

Because the summer of 2025 is not over, it’s not included in the rankings. But as of Aug. 14, the average daily temperature is 74.3 degrees – making it one of the hottest.
Here’s the difference: this year’s overnight lows have been some of the highest ever. The region has dealt with multi-day periods of sustained heat unlike any other year.
“When people talk about how hot it was back in 88, they’re right to do so,” FOX 2’s meteorologist Derek Kevra said. “But what they got was some relief days. We have had very few relief days this year.”
In the summer of 1988, there were seven days when overnight lows fell into the 40s and 26 days with overnight lows in the 50s. The summer this year has had barely any nights when temperatures fell that low. That included a 150-hour stretch where temperatures didn’t even fall below 70 degrees. Over the entire month of July, only three days have fallen into the 50s.
This isn’t the first time I’ve shared Diann’s photo of the coal powered SS Badger steaming out of its home port of Ludington back on Labor Day 2008 & it won’t be the last! Here are a few others that I’ve featured over the years – see more in her Third Coast gallery on Flickr.
National Lighthouse Day is an un-official celebration of lighthouses and the commitment and service of those who tended America’s lights for generations. It’s an especially big deal in Michigan because we are home to more lighthouses than any other state in the country, with over 120 lighthouses keeping watch along the 3,200 miles of Great Lakes shoreline!!
The American Lighthouse Foundation explains that the 1789 Act for Establishment and support of Lighthouse, Beacons, Buoys, and Public Piers enabled a huge amount of commerce by guaranteeing that lighthouses and other marine safety infrastructure would be funded nationally. National Lighthouse Day was officially celebrated on August 7, 1989 to mark the 200th anniversary signing, but Congress has yet to officially name it a national holiday.
Brian took the above shot of the Grand Haven Lighthouse earlier this year & the one below back in June of 2020 – love the way the sun lights the light! See his latest on Flickr.
…“When we get 15 foot waves on Lake Michigan, I’m thinking, ‘Oh, my God. How much damage are they doing?’” says David Bunte, the supervisor for Chikaming Township, near the southern tip of Lake Michigan.
Water levels fluctuate naturally in the Great Lakes but intensifying climate change accelerates those changes. What used to be normal on a 20 year cycle is now happening in five or 10 years, says Mike Shriberg, an environmental policy researcher at the University of Michigan.
“We’re seeing record highs and then record lows much closer together,” says Shriberg, whose work focuses on Great Lakes water policy. “The Great Lakes has already experienced more water level change in the last decade than the saltwater coasts are expected to experience in the next 100 years.”
Ice normally acts as a buffer for the shoreline, absorbing the blows of powerful waves in winter storms, but as temperatures warm, diminished ice coverage in the Great Lakes is speeding up coastal erosion.

If you’re not yet aware of Michigan Sea Grant , I encourage you to learn more about this cooperative program of the University of Michigan, Michigan State University, and the National Oceanic and Atmospheric Administration that funds research, education, and outreach projects designed to foster science-based decisions about the use and conservation of Great Lakes resources.
Mark took this photo at the beach in St. Joseph. Here’s a few more of Mark’s recent shots from the St Joseph’s Lake Michigan shoreline – note the crazy high water! See the latest in his 2025 gallery on Flickr!
Longtime Michigan in Pictures contributor SueFi Photography shared a bunch of photos related to the recent restoration & preservation of the Frankfort Lighthouse after repeated vandalism incidents:
Erin Griebe, the chairperson of the Frankfort Lighthouse Restoration Project, says volunteers first noticed bullet holes in the lamp room last fall. “That’s very expensive glass to replace. It’s all custom because this is a very old historic building, and once the integrity of the glass is disrupted with bullet holes, you have to make those repairs,” Griebe told News 8 affiliate UpNorthLive.
“It’s just years and years of build up and paint and, you know, if we’re going to spend all this money, donated money to entirely clean this down to the bare metal and then restore it to pristine condition, is this just going to happen again?” Ketz said.
The restoration project was estimated to cost $1.1 million in 2022. Griebe already knows the costs will surpass that estimate and wants to avoid any other unnecessary work. “We are hopeful that by raising awareness, people will become less likely to tag the lighthouse, and for the individuals taking shots at it will also think twice now that the community at large is more aware,” she told News 8.
The sun’s brush paints the day’s end with strokes of flowing orange and opalescent coral. Sleeping Bear Dunes, guardian of the coast, stand silhouetted against the celestial masterpiece. As the sun descends, the waters of North Bar Lake become a mirror, reflecting the heavens in all their fiery glory. A ribbon of liquid cuts through the sand, mirroring the sky’s vibrant hues. The wet sand, kissed by the setting sun, flows with ethereal light, a testament to the sun’s final performance. The air, still and hushed, is filled with the gentle lapping of waves against the shore, a soothing melody that accompanies the visual symphony.
Mark Lindsay from The Soul of Sleeping Bear
Leelanau.com shares that photographer Mark Lindsay (whose work you may have seen on Michigan in Pictures) has released his first book, The Soul of Sleeping Bear. It’s a beautiful, coffee table book that blends Mark’s gorgeous photography of the Sleeping Bear with writings on what these vistas can spark in your heart.
EDITOR’S NOTE ON THE EDITOR’S NOTE: I am the editor of Leelanau.com. I wrote the Editor’s Note below and fully endorse the position of the letter writer. Honestly, if you don’t I really wonder why you follow this blog and for sure don’t care if you go away for good.
EDITOR’S NOTE: This is the first message that I am going to share from a National Forest Service employee who is neck deep in the horrors being perpetrated against the National Park Service and the National Forest Service. Sadly, I don’t think it will be the last. Also, at the end, the author says mean things about the Department of Government Efficiency aka DOGE aka the unelected & unaccountable organization taking a wrecking ball to the federal government which I fully endorse. This is an ill-fated & poorly planned action that will cause untold & in some cases irreparable damage to public resources that you and I own. We should not allow this.
1. I still have a job, meaning I somehow cleared level one. RIF (reduction in force) is the Boss Level, and that’s still a ways off (days? Weeks? We don’t know). I am not in any way hopeful that I will still be employed with the National Forests in four months, or that there will be National Forests in four years.
2. People at work are packing, printing our performance docs, waiting for the call. Some of us (like me) have targets on our backs, but nobody is safe. Nobody sleeps. A co-worker thought he was having a heart attack. We compare what meds we’re taking for anxiety. The wait is torture. I had to process termination paperwork for a very close friend who kicks ass at her job. It sucks every day. And work used to be my happy place.
3. The termination letters site performance issues. THIS IS A LIE and they know it. That’s why they fired (and were forced by a federal judge to rehire) the head of the Merit Systems Protection Board, a board whose main job is to say, “Whoa whoa wait a sec. You can’t fire federal employees without just cause!” This is why people are signing termination docs “signed under duress.” My friend has excellent performance evaluations. Most of the fired people do. Because…
4. Probation does NOT mean we did something wrong. It means we just got hired (or promoted) and it came with a probationary period. These are recent graduates who went to school for natural resource management, wildlife conservation, forestry, and did so with the SOLE INTENT of protecting our public lands. These are the MOST devoted, passionate, educated, efficient people. With the least pay. We don’t work public lands for the pay; it is so much less than private sector wages, you guys. Look up the federal pay scale. It’s public information. Compare GS level jobs to what they’d make at a private company. In NPS we joked that we got paid in sunsets. We join because we believe in preserving public land for future generations. But it’s starting to look like our public lands will be cannibalized for parts. So
5. Please! If you go to public lands this summer, or in the next four years, know that we are doing the best we can with the staff and budget we’ve been given. There’s a district north of Yellowstone of over a million acres that has been left with THREE employees. Recreation and Trails departments across the nation have been gutted. There are NO PEOPLE LEFT ON THE GROUND TO CLEAN YOUR SHIT. If you have a complaint about your lands this summer, do NOT get hostile with the federal workers on the ground. Take that complaint, dip it in hot tar, and shove it as far up the DOGEs ass as you can reach.
