rip to the ozone layer but you’re dying in the most beautiful of ways

On Sunday, December 17, the Polar stratospheric clouds were seen all over Finland!

Polar stratospheric clouds (PSCs) are clouds in the winter polar stratosphere at altitudes of 15,000–25,000 m (49,000–82,000 ft). They are best observed during civil twilight, when the Sun is between 1 and 6 degrees below the horizon, as well as in winter and in more northerly latitudes. Wikipedia

The most important reactions leading eventually to the destruction of ozone on PSCs are those that form HNO3, H2O and Cl2 from ClONO2, HCl and N2O5 through the intermediate HOCl.

"No, it’s not a painting and it wasn’t photoshopped either. These are polar stratospheric clouds over Iceland.

The images were captured over the span of one hour at the same place."

Not as mighty as the polar stratospheric clouds in Iceland but nice nevertheless. It looked like a messed up rainbow and divided the evening sky into dark and light sections.

Rare Rainbow Clouds Appear in Iceland Thanks To Freezing Temperatures

These polar stratospheric clouds (PSC) paint the sky with different colored stripes. PSCs are a type of wave cloud that are most often found downwind of mountain ranges. As expected, Óskarsdóttir's stunning rainbow cloud images feature prominent mountains. The colorful clouds form when the lower stratosphere hits -114°F (-81°C).

Weekly Update

getting back to studying, SUN, ice ... everywhere, being creative, workshop

13.01.-19.01.2025

Studying

started getting back into a routine and started studying again

looked for summer jobs

had the first meeting for a workshop and it was very nice, I understood like 90% of the Finnish and also spoke mostly Finnish

I need to start studying math next week because I have a workshop about that in a few weeks and I haven't done proper maths in like 4 years...

Languages

I started tracking most of my Finnish studies this week and am pleased with like 7 hours for my first week back to studying

compared to speaking Finnish, English sounds are so uncomfortable to pronounce now because the Finnish pronunciation is very similar to my mother tongues' but English sounds are way more exhausting...

I saw the question 'What 5 languages would you choose to be fluently in immediately if you could?' somewhere on social media and it got me thinking.

First I would definitely choose Finnish. It would make things so much easier and faster if I could already speak fluent Finnish (but I gotta go the long way...)

Then I think I would choose Chinese because it is such a difficult language but it could be useful to me (the chinese mountains are calling me).

Also Russian because I like the language although it is hard and I could also speak with so many more people (it would have been very useful in my last course because there were a lot of Russian and Ukrainian people).

Then maybe Romanian because I would like to travel there too and the language sounds so nice.

And maybe Spanish because it opens communication with soo many more people.

I didn't choose Korean and Swedish (which I am also learning) because honestly, Korean is just for fun and I want to completely go through that process. And for Swedish I honestly think that it won't be too hard because I already know 2-3 connected languages which makes it easier for me to learn it.

Which 5 languages would you choose?

Health

my back is a bit better but not fully, I think its now again connected to sitting too much, so more movement it is...

I understand myself better the older I get and the more I learn and get more intuitive with knowing what I need when I am not feeling well and it honestly is so nice, being able to help myself regulate

For myself

I properly sewed my first little thing! (first time using a pattern and turning the fabric inside out and using filling and sewing sth. shut)

practiced drawing horses and started a unicorn sketchbook spread and holy moly did that make my inner child happy

1 hours traditional hatha yoga. I have never done a yoga session for so long and it was challenging but also very rewarding (at least that day because I had sore muscles for like 3 days after that...)

this week's

reading / watching / listening

The Honey Witch - Sydney J. Shields (would not recommend, sadly the only good thing about this book is that it's pretty)

this Youtube channel where she walks through old chinese places and tells a about their story

Doomsday Blue - BAMBIE THUG

Blue Blood - IVE

Pink Pony Club - Chappell Roan

I also saw polar stratospheric clouds for the first time which was insanely beautiful and so breathtaking (and rare!). Basically rainbow clouds. But they were so hard to capture on camera :(
