Professor of astronomy, farmer of goats. Asteroid (42910). She/her.

Living and learning on the land and under the skies of Treaty 4 (Saskatchewan, Canada). Currently on sabbatical and based in Ōtautahi Christchurch, yelling about satellite pollution in many locations around Aotearoa New Zealand.

I managed to proofread and comment on the entire 6 page American Astronomical Society draft response to Reflect Orbital's reply and also write my own draft response and not throw my laptop out the window with rage over Reflect Orbital's absolutely fucking terrible plans. Please clap.

Do I think this will actually help? No, not really, the FCC is evil and blinded by $$$. Do I still have to do this? Yes. Yes I do.

Everything is terrible, but I'm getting close enough to going back home from the #ProfSamLectureTour that I just added a couple of books to my library queue so maybe they'll be at my home branch waiting for me when I get back to Saskatchewan!
In one week, Kreutz sungrazer C/2026 A1 (MAPS) will reach perihelion just 0.23 solar radii above the Sun's surface. Whether anything of it still exists by then remains to be seen. However, even if its nucleus fully disintegrates right now, the remnant will still rapidly brighten in the final hours before perihelion as intense solar heating turns the dust into a trail of glowing gas likely peaking in integrated brightness at around magnitude −2 about 10 hours before perihelion (Apr 4 ~04 UT). Solar coronagraphs will provide a near-realtime view either way; here's a diagram of the trajectory through the SOHO/LASCO and GOES-19/CCOR-1 fields.

@sundogplanets Note again to my fellow #HamRadio operators...they require a CORES account to make it nearly impossible to comment. And to get a ham radio license, you also got a CORES account. It's up to us to speak for the hundreds of millions they are preventing from speaking.

Go make a comment.

Following up to say... the whole idea is so fucking ignorant that it's all shocking. I'm just focusing on the eye damage issue because it's something they readily admit will cause harm, and it's a concrete calculation (even if I think they did it in a bullshit way that ignores a lot of things that actually make it MORE likely to cause eye damage)

Ecological damage has me far more worried, and losing so much of the night sky for some techbro fuckweasel's pipe dream is just devastating.

Night sky 10 years ago: “look, a shooting star!”

Night sky tonight: “look more Starlink junk burning up and rapidly seeding aluminium into our upper atmosphere with unknown consequences.”

Any journalists want to write about this? Or anyone know how to figure out who insures Reflect Orbital? Reflect Orbital will cause eye damage to people using telescopes, as astronomers have previously calculated, and they openly admitted it in their reply.

(There is a whole slew of absolutely devastating ecological damage they will also cause, but I'm focusing on this one for now because it's so shocking)

FCC reply comments are due by 5pm EDT Monday 30 March on Reflect Orbital. If you wrote in a comment, please please please write in again saying that they did not address your concerns in their letter (which is very hard to find in the FCC dumpster-fire-of-a-website). Instructions here: https://aas.org/posts/advocacy/2026/02/how-submit-comments-satellite-applications-fcc

The most horrifying part in their "consolidated reply": they agree that they could in fact cause permanent eye damage to people using medium-sized telescopes. WILD.

I got to go to an A&P show yesterday (the equivalent of a county/town/agricultural fair in N. America) and HOLY SHEEP. It was everything I could hope for, with the added bonus of a vegetable sculpture contest and the prizewinning alpacas (and cows and horses) marching behind the town's bagpipe band! It ended with a sheep shearing speed contest, where everyone was hanging around drinking beers and taking turns shearing sheep (the shearers were averaging 2 min per sheep. Wow.)
