www.sr.bham.ac.uk/nam2026/sess... Session proposals are now open for the 2026 UK National Astronomy Meeting at the University of Birmingham, with a 19th December deadline. #astronomy #heliophysics #uknam2026

Happy Fountain Pen Day!🖋️

Very nice to see ngGONG move forward! GONG is a decades-old global instrument on which the Sun never sets, to observe the Sun around the clock. It provides very important continuous monitoring of space weather and allows us to image the interior of the star itself. ☀️

Solar Cycle Update: Solar Cycle 25 is still on the downtrend, but July saw a nice uptick in sunspot number. The yellow lines are daily sunspots, blue are monthly, and the red is the smoothed number. #heliophysics

Although active sunspot region 3964 is stealing the spotlight today, AR 3961 located in the southeast quadrant continues to expand and is quietly becoming a behemoth. This region could eventually become a flare producer as its magnetic complexity continues to evolve.

It's a chilly day out there today! ❄️🌨️ But not to worry, tomorrow we'll be bringing the heat when we host two Specialist Discussion Meetings 😎 With the Sun approaching the maximum of Solar Cycle 25, one will look at when the cycle will peak and how active the Sun will be ☀️

As well as the #RASAwards2025, there will also be two Specialist Discussion Meetings taking place on Friday. They are titled 'Dynamos, Dynamics, and the Solar Cycle at Cycle 25 Maximum' and 'Gravitational Wave Analysis in the Era of Machine Learning'. Find out more at: https://buff.ly/4hmNPsn

I think the UK localization in my Windows 11 24H2 has gone ever so slightly awry!

Last day for abstracts for this one-day meeting on 10th January 2025! Join us at the RAS to discuss the solar cycle and dynamo.☀️ #heliophysics www.ras.ac.uk/events-and-m...

If you study #heliophysics then you might want to see this.☀️

I've been running a solar flux/sunspot number reporting bot at @jj1bdx.bsky.social. This bot collects and sends the report every three hours. 🧪

Some of today’s #sunspots. The pic covers about 1/8th of the #solar surface facing us. 🔭 🧪

Bluesky now has over 10 million users, and I was #2,301,501! (After a few months on the waitlist, and not long before the invite system was dropped.) Stilll enjoying Bluesky nearly ten months later.

As we head towards solar max, there are signs that Cycle 26 imminent. A recent study out of the University of Birmingham shows that key signs, known as solar torsional oscillations may already be underway. Here’s our post on the study for @universetoday - www.universetoday.com/167835/the-n...

The huge active region 3780 seems to have grown and intensified a bit since I snapped its photo yesterday. #Astronomy #Astrophotography

I’ve been reading that a very large sunspot should appear on the Sun’s eastern limb early next week which sounds intriguing . Apparently it’s large enough to affect the way the Sun vibrates. See here ➡️ www.spaceweather.com 🔭

Can you believe this is in the centre of a city?

Wood anemone season.

Oooh. There's a new book in the Jani Kilian #SF series by Kristine Smith, which I thought was over long ago. It's called Echoes of War, and I'm excited to read it.

Look at this beautiful aurora timelapse created by ASE member Eros Tang from the beach at Portobello, Edinburgh. 🔭 flic.kr/p/2pjrGkm
