Update on the ongoing geomagnetic storm: the main magnetic core of the 31 May #solarstorm has arrived at Earth starting around 1 June 12 UTC, BUT it is one of those kinds that are VERY unfavorable for #aurora - the field is entirely northward and very likely to remain so for the next few hours.

Looks like that fast CME is here already, about 2.5 hours before our predicted window. Funnily enough, we've just worked out why fast CMEs are often earlier than predicted and will be rolling this into the forecast soon! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

There's a fast CME heading into some fast solar wind and some pre-existing slower CMEs. We're currently putting arrival at noon-to-midnight tomorrow, but this forecast may change as more observations become available. Updates here: research.reading.ac.uk/met-spate/hu...

BREAKING: The president's budget request just hit Congress, which could usher in a dark age for NASA space science. Congress has the final say, but you can help shape the outcome by adding your name to our global petition. This is just the start of our fight. Sign the petition: planet.ly/petition

The proposed NASA and NSF cuts feel like when ISIS destroyed the monuments of Palmyra with sledgehammers. These things not only pay for themselves, they return several dollars for every $1 spent. Kill the science, kill the spin-offs, startups, patents, talent pool and global influence.

The Presidents Budget Request for NASA is out. It’s a bloodbath Canceled are DAVINCI, VERITAS, Juno, OSIRIS-APEX, US participation in ExoMars and EnVision… Huge cut to R&A. No funding to begin development of the Uranus Orbiter. If you’ve ever cared about NASA, time to contact congress.

NEW: Mars, like any world with an atmosphere, has aurora—but they’re ultraviolet, invisible to the human eye. Scientists wondered if visible, green, aurora did exist though. And thanks to Percy the rover, they’ve finally seen them! 🤩 Me @nytimes.com www.nytimes.com/2025/05/14/s...

We’ve just had the largest #SolarFlare of 2025! Is the Sun waking up? Newly appeared active region AR 14087 has been very active today, producing an X2.7-class event (alongside two other M-class flares) in the past 12 hours. This region will rotate to face Earth in coming days.

With the Trump administration's proposed budget we could be saying goodbye to long-planned space missions, new weather satellites, and crucial life-saving treatments. 🧪🔭 www.iflscience.com/trump-admini...

My first image of the Sun in a while, taken this morning from my back garden. The large sunspot group is AR 4079. Esprit 100. x2 Barlow. Herschel wedge. ASI17MM. Continuum filter. Colourised to make it look like we're conditioned to think it should look like! 🙂 🔭

If you have eclipse glasses handy, check out the Sun today and you'll see a Sunspot without a telescope (if you've got modestly good vision). This is a quick pic with my phone, through eclipse glasses

The K2-18b saga deepens with a great new paper out today by @luiswel.bsky.social (arxiv.org/abs/2504.21788). Turns out hydrocarbons can explain K2-18b's new JWST MIRI spectrum without the need to invoke DMS or DMDS as biosignatures. Read on to find out more! 🧵 #Exoplanet 🔭🪐

🚨Our new paper is out now! We caught Jupiter’s upper atmosphere reacting dramatically to a bursts of solar wind, which triggered a planet-wide wave of heat to flow from the auroras. This changes how we think about the Sun’s influence at the outer planets. www.reading.ac.uk/news/2025/Re...
