#ThrowBackThursday Special Issue "Solar and Stellar Flares: Observations, Simulations, and Synergies" / Edited by Lyndsay Fletcher and Petr Heinzel: link.springer.com/journal/1120... Published 2015 in #SolarPhysics, with highly-cited contributions to a conference in honor of Zdeněk Švestka.

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...

MSc & PhD positions in #heliophysics and #exoplanets at Mackenzie University, Brazil. Applications deadline May 13. Scholarships available - please get in touch (DM me!) for more info about this and projects! We can also talk about posdoc positions #AcademicSky www.mackenzie.br/processos-se...

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...

Having a great week at @issibern.ch with these amazing scientists discussing The Impact of Solar Flare Irradiance on the Earth's Ionosphere

I am very honoured to have been awarded the James Dungey Lectureship by the Royal Astronomical Society.

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...
