Happy first day of school, and thank the stars for bus drivers! One of my kids just got on the bus (which comes *to my back door* ridiculous luxury!!) My other kid will get on a different bus soon, that also comes right to my back door.
Related to yesterday's shit-show of car-dependence: Saskatchewan has one single type of rural public transportation figured out extremely well. I sure wish they'd give us grown-ups some options, too.

My goats love their straw bale playground equipment. And Goatzilla says "yes, these apples you poured out for us are very nice, but can you please hand-feed me instead? I am very spoiled."
Also, my goats would like to tell everyone that genAI fucking sucks.

😭 😭 😭 apparently the university IT people failed to turn off the built-in Zoom chatbot that tells students everything in the lectures without them ever having to watch the lectures. Classes started today. I am currently feeling grumpy enough to wonder if I it would be less work to "poison" the chatbot by uploading a bunch of fake, incorrect lectures to my Zoom account rather than trying to download everything and upload to another platform like... tomorrow.

A flat tire on my stupid plug-in hybrid car that doesn't have a spare was definitely what I needed on my first day of teaching for the semester. FUCK. $100+ taxi ride? Or risk the scary farm truck that is likely to die at any moment? The currently required car-dependence of living in a rural place really really sucks. I should get a horse.

(I realize there are huge accessibility issues here to adding in-person exams - but I will work with individual students as much as I can to fix those. There's an excellent accommodation centre on campus which I will utilize to its full capacity next semester)

thank you for kind words. Today didn't go *well* exactly, but some small victories.
Big organization that I helped write an FAA comment for won't send it, so a bunch of collaborators are signing it as individuals and sending it anyway.
My college dean is very supportive of making online classes not go well for students who use genAI. So now I have in-person exams added to my online classes that are locked in for next semester, and my classes for next year will likely all be in person.

Cried in frustration over my emails at 7:30 am on a Monday morning about stupid shit that's going to happen in orbit and my inability to do anything about it, and my apparent inability to even organize others to do anything about it. It's going to be great week, I can tell.

Got roped into helping an elderly neighbour pick plums off multiple trees. Definitely didn't have time to do that, but it was really nice chatting with her, she let me pat her hairless cat (!!) and now I have probably 50 pounds of really tasty plums that I need to figure out what to do with (a very good problem to have).

Revising a conference proceedings paper (from over a year ago...) and when I submitted it there were fewer than 8,500 Starlink satellites in orbit, out of about 12,500 total satellites.
Today there are 11,102 Starlinks out of 16,978 total active satellites. Fuck.

This course is a 3rd year physics major course in astronomy, in a university that doesn't have an astronomy major. So I had to figure out how to do a decent deep dive into a few topics. I picked a handful of research papers, both new and historical/significant, and we'll do a deep dive on each of those topics! And now that I've sorted that out, I have "supermassive black hole" stuck in my head...

2026-08-30 04:23:22 CEST

I managed to get the course page up and running for the *other* course (that's not online and doesn't have videos that got sucked in to Zoom's genAI system). Much easier, but I couldn't find my notebook with all my lectures in it from 3 years ago, last time I taught this class. So... if it's not in my campus office, I'm going to be extremely sad and have a LOT of work to do. If it's there, I'm all good to go for the semester!

We saw a badger in the garden! And I tried really hard to take a picture of it! And.... if you squint you might be able to convince yourself the blur in the middle of the picture is a badger!
(I am happy to have badgers, because they eat rodents that eat my garden. I just hope the badger is not hanging around during dog walking time)

All the cabbages and some tomatoes picked. Some flea beetle damage for reference (and this is really the first day they've been bad, they did this in <24 hours). And happy goats in a new eating area. Yum, rose bushes.

The Flea Beetle Apocalypse* has started, so today is harvest-all-the-brassicas day. I also need to move the goat fence, pick tomatoes, help with harvesting garlic, and deal with the Monster Zucchinis that are probably lurking where I haven't picked for a few days. Will feed those to goats with a visiting friend.

I don't have enough time to move to a different video platform at this point, and they're all too expensive (or too hard to get started on) for the bandwidth my class and a few other online classes need (which my college admin *did* say they would pay for if needed, even though they shouldn't have to do this!)
I'm pretty convinced this is my last year teaching online classes. Oh well, it was a fun experiment while it lasted.

An update on this for anyone who's curious: enough professors made enough of a stink that the IT people figured out how to turn off the student-facing built-in AI chatbot (so they claim, it was still working as of yesterday), and they said they would delete all the AI-generated summaries and chapters that appeared in my lecture videos (though they have not done it yet).

Nothing like a surprise in-person national news interview to make the day even more fun... but hey, it was about the eclipse and the beautiful night sky (must be a slow news day), not terrible things happening in orbit, so I'll take it. (Of course I did talk about freaking many satellites I saw while watching the eclipse... but the eclipse was still cool. Will be at least a little bit longer before Reflect Orbital and copycats drown that out as well.)

Hopefully that incredibly beautiful naked-eye astronomy time last night will keep me from losing it and crying during any of the many stressful, depressing meetings that I have today. (Unless I think too hard about all the satellites that I saw... which is the topic of at least one of the meetings so far...) I'll be on campus most of the day so I can't even take a hayfield-rage-screaming break...

I don't have a good setup for more zoomed-in astrophotography, so please enjoy these wide-angle photos of the peak of the eclipse last night. The moon looks freaky in a very different way than it did with my eyeballs. It was also so super neat to see the Milky Way overhead while the full moon was in the sky! (Can't usually do that, the Moon is too bright.)
A teacher friend brought her kids over, they said "blood moon" was not a good name, and declared it the "ketchup moon"

I have no idea how I'm going to accomplish even half of the things I'm supposed to do in the next month. I feel rather paralyzed at the moment. I have so many farm things (bringing in the straw tonight, harvesting/preserving all sorts of veggies, moving the goat fence ever-faster on grass that's drying up and not growing anymore). My kids start school next week. My teaching is going to be a fucking disaster this semester. And I have to write a new research grant. Fuck.

A few good suggestions so far, but here's more info because the questions made me realize I really didn't include enough:
I just want students to be able to watch pre-recorded lecture videos, semi-private. I don't want them to easily download videos (not sure if that's a silly ask), or easily feed videos/transcripts into gen AI. I DEFINITELY don't want them to have a built-in gen AI system that knows the video contents that they can get homework answers from.
My university uses moodle.

I eventually want to just make all my lectures public and post everything somewhere public, but that's not happening in the next 6 days for a course that I'm not even teaching myself.
Or maybe I just stop teaching online courses, which I originally started doing during the early pandemic days, then kept doing becuase it makes less work for the underpaid sessionals who teach my classes sometimes.

2026-08-26 20:18:32 CEST

My university ditched the embedded video system they were using for online courses for "Zoom clips" and it's fucking stuffed to the gills with AI features that will make it so students don't actually learn anything - there's a fucking homework cheat "helper" built right in that summarizes lectures and gives you homework answers.
I desperately need recommendations for another way to do this.

I tried making a plot to sort of demonstrate crowding in orbit that would be caused by the 5 companies that have now asked for tens to hundreds of thousands of satellites on sun-synchronous terminator orbits. I wanted to show equator-to-pole, but there's so damn many satellites in all of these I had to show a narrower range of angles in order for the points to not all run together. Anyway... here's what the techbros want for us in Earth's new rings they want to construct

I can't even adequately explain the rollercoaster of emotions I go through looking at these tourist astronaut websites. I always wanted to be an astronaut, I love scifi.

But knowing *who* is buying these tickets, and who the money goes to, and the environmental footprint... ugh. It all makes me feel vaguely sick.

Oh look another Reflect Orbital interview request in my inbox. SIGH.
But I will keep doing as many of these interviews as I possibly can. Because Reflect Orbital is an incredibly stupid, awful, destructive, dangerous idea with no measurable benefits.

2026-08-19 18:05:42 CEST

That was one of my favourite interviews I've done about Reflect Orbital. The journalist (who it turns out has a background in optical engineering) actually had to stop the interview when I explained that Reflect Orbital's mirror is really, truly just a stretched piece of mylar and go on a rant about how incredibly stupid this whole plan is.
Now if only someone with power to stop Reflect Orbital would have that same reaction...

Ok that was a bit much, but was all quite fun. But the highlight was definitely when I stopped at the feed store on the way home (yes I had a fancy telescope and chicken feed in the back of my car at the same time. I'm cool like that.)

I agreed to do a film shoot tomorrow for a university promotion thing, where they wanted me to set up a telescope and look "professorial". I figured as long as I was setting up a telescope anyway, I might as well do some sidewalk astronomy with a solar filter for whoever walks by.
And then they sent out a university-wide email inviting everyone to come look through a telescope at the sun. I guess I'm going to set up TWO telescopes and hope that someone else will show up who can help me...

And the satellites were BAD. Not that much worse than at home, actually, which surprised me a bit.
What also surprised me was how many random bright flashes I saw: these are from tumbling pieces of space junk. There seemed to be a lot more than I've ever seen before.
Relatedly, my collaborator emailed me over the weekend to let his co-authors know that the CRASH Clock is now down to 2.2 days. WEEEEE.

Time to print a couple of maps, pack the car, and start driving towards Grasslands! It's cloudy and a bit rainy here and there (not here at the farm where we really need it ☹️ ). Supposed to get gradually more clear through tomorrow night. Big Fancy Camera is coming along on this trip, though I will definitely regret bringing it while backpacking!
I hope that getting to a very dark place will be calming and not just infuriating as I watch the dozens of naked-eye satellites crawling in the sky.

I don't WANNA write another fucking FCC comment about YET ANOTHER fucking stupid awful destructive "orbital data center" megaconstellation that uses the EXACT SAME fucking orbits as the other 4 fucking stupid awful "orbital data center" megaconstellations.
The "best" part: this one is called...
Orbital.
Because that's NOT confusing at ALL.

Yay new grass for the goats! The rotational grazing gets harder and harder at the end of the summer - the grass isn't growing as fast and I have to move them more frequently.

Relatedly: does anyone know how to find topo/trail maps of southern Saskatchewan that aren't paywalled inside some hiking review website? Acme Mapper is ok, but not great...

Ok, decision made: going camping with my kids tomorrow (even if there's a little bit of rain tomorrow, Saturday and Saturday night are clear!)
My brain needs this. Wow I'm doing a *terrible* job focusing on any of the zillions of things I'm supposed to be working on today.
(Major downside of farming with animals in a place I have no family but everyone else does, I don't have anyone to cover animal chores for a night. So my partner and I only get to do separate camping trips. Sigh.)

Good morning from my cute animals.
The mama goats wanted to immediately head down to the eating pen after morning milking, but were caught by their giant-and-still-nursing babies, so they patiently chewed their cud and let their giant babies nurse. Looks hilarious!
Devil Cat (actually a very nice barn cat) is very hard to photograph because she doesn't stay still for more than a split second.

RE: https://mastodon.social/@sundogplanets/117067760073867737
I was really hoping to go to Grasslands tonight and get some amazing stars (and Perseids! And maybe auroras! And a fuck-ton of satellites!), but the next 2 nights are rainy.
Good, because we need rain. Bad, because I wanted to take my kids backpacking at infinity's doorstep!! Hopefully I'll still get to go in a day or two...

Now that the eclipse is over and lots of people saw it: did anyone notice any satellites moving across the sky during the eclipse? (Our paper from a couple years ago predicted that maybe possibly you could see some)

I got a few profs from the meeting I was in to end early and look up at the teeny tiny bit of solar eclipse through eclipse glasses. Outreach done!

2026-08-12 16:22:00 CEST

Starting off the morning with a live radio interview about the eclipse and the Perseids, and an opportunity to respond to completely fucking useless official statements from Reflect Orbital (which I managed to do without swearing in my response, please clap).
Now I need to go to campus for meetings. I'll bring some eclipse glasses along, but the 0.09 eclipse from here will be extremely underwhelming. Those of you in the path of totality: ENJOY!!!

2026-08-11 18:07:16 CEST

COOL apparently the American Astronomical Society journals (the Astrophysical Journal/Astronomical Journal/Planetary Science Journal) have refused to even review our article on satellite brightnesses (already posted on arxiv https://arxiv.org/pdf/2608.02757) because it's outside the scope of astronomy. Time to go rage-scream out in the hayfield, I guess.

Good article really tightly focused on how Reflect Orbital is going to damage people's eyesight and actually has no plan for how to avoid that. I need to watch that instagram video again... which I apparently pasted the wrong link to above. Oops. Boy it's been a long morning already.

First (only? maybe?) interview of the day done with [@astrojonny.bsky.social](https://bsky.brid.gy/r/https://bsky.app/profile/astrojonny.bsky.social ). I tried to channel this person's delightful fuck-you-reflect-orbital energy that was shared with me by another astronomer: https://darksky.org/news/darksky-and-allies-ask-the-fcc-to-reverse-its-approval-of-the-reflect-orbital-space-mirror/
The other interview I was maybe going to have got cancelled when I explained that a 10% solar eclipse is probably not something that people are really going to want to look at...
Here, have some chicks. It's going to be a long day.

Do I want to try to set up some kind of public viewing for a 10% solar eclipse when I am feeling rather burned out on public outreach? Or, to phrase it differently, if I don't set up a public viewing will I manage to not feel guilty for it?
Another local new interview scheduled to talk about this tomorrow. Sigh.

This is the sky Reflect Orbital wants for us, so they can make money: https://starryprinceton.org/scattering_calculations_renderings
They don't fucking care if you can see the stars. They don't fucking care if they damage people's eyes. They don't fucking care if they cause car crashes and plane crashes. They don't fucking care if they disrupt ecosystems and human sleep. They just want money.

Last night, I stayed up later than I've managed for a while because the skies were finally clear. Milky Way, Andromeda Galaxy, a whole bunch of Perseids, and absolutely stunning numbers of bright satellites. Even keeping track of the number of new satellites does not prepare me for what I see crawling across the sky every clear night, like swarms of unwelcome insects in my home.

I am TOTALLY enjoying reading all these stories of awe and wonder as we get to gaze over "infinity's doorstep" with our own eyes.
This is what I am fighting for! This is what I want everyone to be able to do! It often feels like nobody cares about losing the sky, so reading how much it means to lots of people is incredibly energizing. Thank you, keep the stories coming.

Oh I should add to my own personal list: the multiple aurora shows over the past couple of years that I've been able to see from my own house! May 2024 and especially November 2025 were completely mind-blowing.
I found myself joyously whooping and yelling at the sky. I kept thinking of the Cree name for a really active aurora show, cı̂payak kâ-nı̂mihitocik, which translates to "the ancestors are dancing". It was truly an emotionally powerful event to bear witness to.

Where is the best, most incredible, most perspective-shattering night sky that you've ever seen?
For me, it was the Tekapo dark sky reserve in New Zealand a few months ago (I got up at 1am both nights I was there specifically so I could get some mostly satellite-free skies to enjoy).
Second place: Mojave desert many years ago (before megaconstellations) or winter skies about an hour outside Regina, when the nights are long and there are no sunlit satellites due to geometry.

The world would be a much better place if everyone had easy access to infinity's doorstep, to realize how small we are, how unique and fragile our pale blue dot is.
You don't need a trip on a billionaire's rocket to get the "overview effect." You can do it by finding dark sky access, which is becoming harder and harder to get, partially due to billionaires' rockets.

"At night this reassuring curtain of blue is pulled away and you realize where you really are: at infinity’s doorstep. A plain is what a mountain aims to be: the closest you can come to being in outer space while yet having your feet on this planet."
I really hope to get out to Grasslands Nat'l Park this week and appreciate infinity's doorstep, despite smoke and satellites trying to take that away.

A stunningly beautiful quote from Yann Martel, sent to me by a satellite engineer who loves the sky:
"If you’ve never been, the south of Saskatchewan is so flat the horizon is perceptibly round. Above you, during the day, lords an immense dome of sky so empty it feels like a fullness, with clouds the size of mountains, the sun but a small disk, and a depth of colour that is often chalk blue, oh so chalk blue.

Most city dwellers don't know how much of the night sky has already been stolen by billionaires, because poorly planned, wasteful city lights have already drowned out the stars for them.

The last purple martins have fledged (and are turning up in various silly places around the farm, like this guy just hanging out in the fence).
The swallows, purple martins, and crows are gathering together into larger and larger flocks, and thinking about leaving. It's always so sad when the birds leave us for the winter, and mid-August always seems awfully early. But, well, it's Saskachewan. Winter is coming.

And more chicks have hatched! We had 17 hatch a few days ago, and 9 more have hatched from this last batch so far. I think we'll get a couple more, then hatching is done for 2026.

Reflect Orbital is just such a dangerous, ineffective idea. The list of binding conditions that they put in the Application for Review (see link above) really powerfully shows how dangerous it truly is. I can't believe that any government regulator would say that this is ok to launch, there are SO MANY THINGS that could cause immediate, significant harm to humans, and long term massive environmental damage (and that's ignoring astronomy)

2026-08-06 23:41:03 CEST

Earthjustice submitted an official "Application for review" of the FCC's approval of Reflect Orbital for launch. It's submitted on behalf of DarkSky International, Environment America, Public Employees for Environmental Responsibility, and the American Bird Conservancy.
Gosh I hope this will actually cause the FCC to review their decision.... https://darksky.org/news/darksky-and-allies-ask-the-fcc-to-reverse-its-approval-of-the-reflect-orbital-space-mirror/
