The pains of a comet observer... and I bet, Saturday will not realize, too.

I wonder what the Republicans in Congress that still pander to this pathetic, vain, deluded, narcissistic, embarrassing old man's every whim must feel when they look in the mirror. The world is laughing at you, USA. It's scared as well of course. But it's still laughing at you.

Donald Trump complains about his picture on the TIME cover on Truthsocial: éh Donald J. Trump & © —
@realDonald Trump
Time Magazine wrote a relatively good story -
about me, but the picture may be the Worst of 
All Time. They “disappeared” my hair, and then 
had something floating on top of my head that 
looked like a floating crown, but an extremely iE 
small one. Really weird! I never liked taking 
pictures from underneath angles, but this is a 
super bad picture, and deserves to be called 
out. What are they doing, and why? y

This was the best the sky was able to show today. Now it is completely overcast again.
Spend the afternoon with some high-end escapism: started a new playthrough of Pillars of Eternity 2.

While I am absolutely not superstitious, the sole reason for this mess is that I printed the comparison stars already yesterday evening and left the eyepiece in the scope.

New animation of the ultimate engineered solar system for a talk I'm giving tomorrow at a sci-fi convention in Lithuania.

It has 400 rocky planets in the habitable zone of a single Sun-like star

It's perfectly stable (I simulated it out to about a billion years)

1 hour after my observation last evening, clouds rolled in and this morning it is damp and grey. Still, the forecast says clear skies this evening. This time of year weather is a lottery. Forecast models struggle with such a situation. Let's see what if I win the lottery this and tomorrow's evening.
comethunter.de
C/2025 A6 (Lemmon) is now also visible in the evening sky - but much lower than in the morning. Estimated it 6.0 mag, probably brighter. Tomorrow evening I will "climb" the local mountain trying to obtain my first view of C/2025 R2 (SWAN), which will be below 10°. It will rise higher day by day.

This is remarkable. The world added more solar and wind capacity in 2024 than we added demand. 100% of demand growth PLUS 9% to retire dirtier sources. Cheap energy keeps winning. ember-energy.org/latest-insig...
