Picked up my 30th Potentially Hazardous Asteroid last shift. This one is interesting. In a retrograde comet-like orbit with a period around 26yrs but showing no activity at ~1 AU from the sun. Likely 1km + in size with Earth MOID = 0.0275 AU. Now published as 2025 VP.

New morphology in the tail of comet 3I/Atlas will inevitably be spun by the quack Avi Loeb as some evidence of alien activity. This is nothing new, we've seen similar behavior in other comes including 17P, C/2016 R2, and C/1961 R1, and others. It's ionized carbon monoxide. #3I #3I/Atlas #Comet 🔭

This is how they deal with pedos in the UK. In the US, Christians make them POTUS.

Such a "good book". There's a reason they don't actually read it. Probably the same reason they won't directly quote Kirk.

Hurricane #Melissa made landfall still intensifying. It hit the coast of Jamaica in the top 3 (tied for mb) strongest storms in Atlantic history at 185mph winds and 892mb pressure. Very compact but extremely powerful storm. It is crossing the island maintaining cat5 intensity.

Hurricane #Melissa maintaining insane strength due to deep warm ocean temps and little shear. Very cold -80c cloud tops have circled the entire storm. Still 175mph beast on track to hit Jamaica.

As of 5am EDT #Hurricane #Melissa is now a cat5 hurricane with 160mph sustained winds. Will cause catastrophic damage to Jamaica over the next 24 hours.

Heart goes out to the folks of Jamaica and other nations threatened by hurricane #Melissa. Another insane run of rapid intensification fueled by human driven carbon emissions into our atmosphere. This is the new norm. Last update was cat4 -145mph. Sat imagery is looking like cat5 intensity.

I might just live in a box of befuddlement, but I find it extremely wild that we live in the 21st century and sheep herders from 2000+ years ago are still defining how we imagine the world to be.
