Well written, fantastic new review paper by Krämer et al. on the high speed jets formed at the collisionless shocks. These jets can have important space weather consequences as they can change magnetic field orientation in the magnetosheath and force dayside reconnection, geomagnetic pulsations and even trigger a substorm during seemingly quiet solar wind conditions especially when interplanetary magnetic field contains large scale (about 2 Million km in wavelength) poloidal fluctuations in Bz and Bx, where an interval of southward IMF is followed by northward field and mostly radial IMF period (Bx dominating). The jet formation favors radial IMF but the jets can generate even - 30 nT southward field in the sheath during the northward IMF! Link in comments as X prevents direct sharing…

All you want to know about those jets you'll find in a new review paper by Eva Krämer of @umeauniversity and others. doi.org/10.1007/s11214…

Much research has been done in recent years on these dynamic pressure enhancements, which we review in this publication. We now know more and more about the intricacies of jets, but there are still many unanswered questions! Thanks to all our co-authors for this undertaking!

I'm happy to share that our review paper on jets downstream of collisionless shocks has been recently published! #Bib1" target="_blank" rel="nofollow noopener">link.springer.com/article/10.100…

On the Night of Science 2025 @tieteidenyo in January, all of our activities are in both English and Finnish! Check out our programme here (scroll down for English): tieteidenyo.fi/fi/ohjelma/geo… Event is free, space is accessible, suitable for all ages! @KumpulaScience @KoneenSaatio

Happy to share that our new paper was published online already earlier this month. It deals with the effects of data-driving and modelling prescription on magnetic flux rope evolution and interpretation of its (in)stability. Read here: doi.org/10.1051/0004-6…

Our new paper on The Interplay Between Collisionless Magnetic Reconnection and Turbulence published in Space Science Reviews! We discuss all manner of interaction between reconnection and turbulence and there is even a primer on turbulence theory basics. link.springer.com/article/10.100…

I'm mainly over on bsky now, find me there: bsky.app/profile/jonass…

The program of the Night of Science is published! ✨ Check out the details at #ohjelma" target="_blank" rel="nofollow noopener">tieteidenyo.fi/en#ohjelma. #NightofScience is a city-wide event dedicated to science, taking place across Helsinki on January 9, 2025.

No new NASA/Solar Dynamics Observatory data will be available for an extended period of time as the server room in the Joint Science Operations Center at Stanford University is currently flooded. Here are the last pictures taken of the Sun. Hopefully it doesn't go nuts now...

Repost this if you’re doing a PhD. I want to see something.

Happy to present my poster on magnetic flux rope identification and analysis at the European Space Weather Week 2024. If you didn't get a chance today and are still interested in my work, tomorrow is one last opportunity to catch me at poster SWR2-p35! #SWATNetProject

Arvostettu ERC-rahoitus maan magneettikentän heikkenemisten ja kääntymisten tutkimukseen! 10 M euron @ERC_Research Synergy Grant -rahoituksen saaneessa projektissa auringon kaasukehää ja heliosfääriä mallintavaa tutkimusryhmää vetää @EmiliaKilpua. Onnea! helsinki.fi/fi/uutiset/ava…+

Immanuel Christopher Jebaraj has been awarded the prestigious Vincenzo Ferraro Prize for young scholars in Space Physics. The award ceremony took place on 13 Oct in Sorrento, Italy. Congratulations! 👏✨ utu.fi/en/news/news/s…

Our division's ECS team is organizing a campfire event for early career researchers with the theme "How to convene a scientific session". For more details and registration link check here 👇🏼 blogs.egu.eu/divisions/st/2…

Unfortunately, the account of @SWATNetProject has been compromised and thus is not accessible any more by the editors. We could not restore the access which is a big loss for us. But we still want to engage with you, 530 followers, on the X platform!

University of Helsinki has published guidelines for it's researchers on the use of generative #AI in research. The guidelines are available for everyone to read on the @helsinkiuni website. helsinki.fi/en/research/re…

Last week I travelled to the stunning Amalfi coast in Italy to become the 17th recipient of the Vincenzo Ferraro award for young researchers in plasma physics. This includes my PhD research in @CmPA_KULeuven and @ORB_KSB, and post-doc in @PhysUtu.

Auroral *occurrence* over the last 375 years has changed as a result of the Earth's magnetic field and solar activity. But auroral *reporting* has a human element; it requires occurrence overlapping with population. And very recently, tech. mathewjowens.github.io/publications/p…
