Do the Hawaii surveys do the same?

Nice find. Yes, your Mt. Lemmon Survey was first. Thanks for finding all these interesting rocks. It seems like there's been quite an uptick recently. Sep & Oct always produce a lot. It is the increase in night time hours, non-crowded Milky Way background unlike summer months or something else?

After last week's asteroid buzzed over Antarctica, the North Pole gets its turn. Newly-discovered #asteroid 2025 TQ2 (2-4 meters wide) passed 3,000 miles above the Fortress of Solitude. #Astronomy

It's now known as 2025 TF, and passed 410 km above the penguins. Previously, there was 2020 QG at 3000 km. And if you want to start a debate, the "Great Fireball" of August 10, 1972 passed through Earth's atmosphere before returning to space. I think there were a few others, but I could be wrong.

Interstellar #comet 3I/ATLAS is hidden on the far side of the Sun from Earth. But today it sweeps past Mars, where orbiting spacecraft have ringside seats. Let’s hope they look up. #astronomy #NASA

It 1-2 meters, so yeah. Nice light show for the penguins and maybe a small sonic boom.

If you were in Antarctica, here's the #asteroid's path across the twilight sky.

An #asteroid passed just 300 km above Antarctica earlier today. It was not discovered until hours after close approach.

10 #asteroids passed closer than the Moon in a 5-day period from September 23-28. All were discovered this month. The largest up to 41 meters wide. #astronomy

You might catch 3I in December.

October's comets. SWAN C/2025 R2, and Lemmon (C/2025 A6). Our interstellar visitor 3I/Atlas aka C/2025 N1, is unfortunately on the wrong side of the Sun for viewing, but I included it anyway because... well... it's interstellar. #Astronomy

#Asteroid 2024 YR4 has a ~4 % chance of hitting the Moon on Dec 22 2032. A strike could spike micrometeoroid flux in low Earth orbit ~1000×, endangering satellites—so researchers even study nuclear disruption. arxiv.org/pdf/2509.12351
My sim: 2000 clones; 72 hit.

#SanFrancisco Earthquake just now. Shaking started before the cell phone alert sounded.
