Ooh, that sounds like a nice idea! I guess you'd want to come up with a weekly or monthly index (average sunspot number?) in that case, though, otherwise it will be /a lot/ of work 😅

After the holidays 🎄🎅🎆 its time to submit abstracts to the @egu.eu General Assembly 3-8 May 2026 in Vienna!
👇Our team at the Austrian Space Weather Office convenes 4 sessions - from solar storm ☀️💨 evolution and forecasting, to research to operations (R2O) efforts and machine learning 🤖techniques.

It kind of feels similar to a PhD thesis in that right now I never want to see it again, but someday I'm sure I'll be proud of it

Ends still need to be woven in, but that's the 2025 daily maximum Kp-index blanket done

Thank you!

Thank you!

Well I successfully defended my PhD, and then successfully survived the after-party

Thank you 😅

Defending my PhD this Friday.

Looking forward to it but also greatly looking forward to it being over 😅

Congratulations!

Look at how round this bird is!!! Bird of the year!!

Bird of the Year voting opens tomorrow, and it is an outrage the takahē is yet to win. I'd like to take this opportunity to urge you to vote for the hide-and-seek legend from Fiordland, the roundest birb, and the one true pick for all you railfans out there

4-panel Comic. (1) STUDENT: If the wavefunction only collapses when I observe it, does that mean my consciousness affects the universe? (2) [Bad:] PROFESSOR: Yes, quantum entanglement proves that we all have souls. (3) [Good:] PROFESSOR: No, consciousness plays no role here. It’s just physical measurement. (4) [Chaotic:] PROFESSOR: No. The wavefunction collapses when *I* look at it because I’m a full professor. It won’t collapse for an undergraduate.

My PhD thesis has now been submitted for pre-examination 🎉

Which means that it's time for me to take some time off 🌴

Just heard from @tmelnik.bsky.social that DSCOVR is offline. Recovery attempts have not been successful. It's going to be a significant, if not permanent, outage.

Halibut Crochet Pattern (U.S. National Park Service)

TIL (on mastodon) that the US National Park Service has crochet patterns!

AGU is deeply disappointed in SCOTUS decision to overrule the order blocking the dismantling of fed agencies until we could make our case about the President’s unlawful actions. 

The harm this will cause is shocking. However, we will continue to fight for the rule of law.

NASA begins push to slash workforce with more staff buyouts, early retirements as budget cuts loom NASA employees have until July 25 to decide if they'll stay or go.

NASA Goddard is pushing through a 48% staff reduction!!! This could impact the upcoming Roman Space Telescope and many other future Astro missions. News coverage seems not sensational enough. Are we really going to let NASA (as we know it) die quietly? www.space.com/space-explor...

Today I gave a seminar on the topic of my doctoral dissertation, and with that, I have now completed all of my doctoral studies.

... Aside from the thesis. Still gotta finish writing that. And then defend it.

Breaking space news: We have made our own solar eclipse in space! 🌘

Today, we release the first images from our Proba-3 mission, which flies two spacecraft in precise formation to create artificial solar eclipses in orbit.

Inspired by @jtuttlekeane.bsky.social and @ohdearz.bsky.social, here's what the White House proposed budget cuts to NASA would do to the entirety of the agency's Science Mission Directorate.

Bloodbath is right.

I'm excited to share that I was awarded the the Marie Skłodowska-Curie Postdoctoral Fellowship! Starting this October, I will work on plasma shocks in the heliosphere at QMUL. Looking forward to new endeavors!

THIS FRIDAY: Can we halt the illegal mass firings of our federal scientific workforce?

We will argue in District Court this week for a temporary restraining order on the execution of Trump’s Executive Order.

It feels like they're trying to turn universities into degree factories.
