I hope that everything will go well for your father and that you will have the strength to deal with it.

They have enough money to buy electricity from France. In the meantime, they will reconsider their "Nuclear phase-out policy" like DE and ES...

Very interesting! 66 is close to the old, average limit of retirement. This might go up as society proceeds to new higher limits. 32 or somewhere there, is also a turning point on how one thinks and sees the world. I tend to agree. I will read the paper for more.

Well, that explains a lot. Bugs everywhere. We were forced to leave Win 10 (the "ultimate" and "final" software) for the crappy Win 11. One can't even rename files without problems. Good job! Well done! 👍🤧🤡

9-11 of #November, a #storm system passing from W to E #Greece, offered plenty of #Sprites and other #TLEs as well as #stormscapes. A 7' video with a lot of smaller and bigger "surprises" youtu.be/qCuxQWnBJlE?...

#Aurora was observed down to southern #Greece (38 deg. N), before dawn on Nov. 12, during the G4 #geomagnetic storm. Faint red, behind clouds, but clearly visible esp. during the 2nd half of the video: www.facebook.com/reel/1288642...

Dst during this period, was free falling from +33 nT to -238 nT.

I hope they are only claims, but I guess it's true. Reality precedes Hollywood.

It's one of those nights, when you forget everything bad and you remember why it's worth living for. For me it's the escape to nature, for others it's something else.

Thank you! You have amazing storms there though, so let's trade some storms for some more TLEs 😁

Yes, I can fully relate. The same applies here. 70 km just to have a relatively decent night sky... and that only towards the south 😢

This is great! 🤩

The outskirts of Munich have Bortle level 4-5 skies (based on this lightpollutionmap.app), which is nice (considering the fact that I tried from downtown Athens with level 9 😅)

Zodiacal light prevails 1.5 hour before sunrise, over the (very bad lighting of the) Temple of Poseidon. Easily visible with naked eye. Jupiter is the bright dot on the upper part of the photo.

Dusk-to-dawn 24-25.10.2025. Cape #Sounion. Lots of clouds still for the comet though. It's the 3rd consecutive week (yes, the thing that carries 7 days with it) that it's not possible to shoot it. Tell me about "sunny Greece" blah blah blah... 🤪 I just want 1 (one) clear night.
