Some pictures of the Total Solar Eclipse from Burgos, Spain. The corona was a sublime golden colour rather than the usual pearly white, a naked eye prominence was visible above the eastern limb, and it was bookended by two glorious diamond rings, all in under 2 minutes. Unreal.

Having a very stimulating and productive meeting on The Impact of Solar Flare Irradiance on the Earth's Ionosphere at the International Space Science Institute (@issibern.ch) in Bern, Switzerland with these fine people!

Ever wondered what powers a solar flare? 💥 Solar Orbiter is finally giving us answers to this long-standing mystery. The mission caught a 'magnetic avalanche' on the surface of the Sun just before a flare was released. 🔭🧪1/3

Nice to see a paper led by one of my PhD students getting the Editor's Choice in Solar Physics! We looked at Doppler shifts in Si III during solar flares using SORCE/SOLSTICE data. There also appears to be a longitudinal dependence on velocity, which may or may not be instrumental...

My PhD student Aisling O'Hare has published her first paper studying the impact of QPPs in solar flare emission on Earth's atmosphere. The ionosphere is much more sensitive to small changes in EUV irradiance than previously believed as measured by changes in total electron content. 👏

This Saturday, between 10am and noon, a partial solar eclipse will be visible from much of the UK and Ireland (weather permitting). QUB/ARC are hosting an event at the Ulster Museum where we will have eclipse glasses and solar telescopes. Come along! www.ulstermuseum.org/whats-on/cha...

Our paper on the instrumental discrepancies on solar flare observations in Lyman-alpha emission, led by Harry Greatorex, has now been published in Solar Physics: link.springer.com/article/10.1...
