It’s important to remember that although active region 3664 *did* produce 10 X-class solar flares, only half (5) of these would have classified as X-class under the pre-2020 calibration. The benchmark for the strongest flare class has changed significantly (lowered by 30%)!

Boom! The largest solar flare of this solar cycle is currently in progress. An X8.8 from sunspot group 3664 just as it rotates off the disc. Complex solar radio bursts also detected by I-LOFAR.

We are delighted to announce the opening of the call for abstract submissions for ESWW2024! The call for early submissions closes on the 6th of June. Find more information on our website: esww2024.org/info-guideline…. #ESWW24 #SpaceWeather

annnndd.... it's back 👀 NOAA AR 3664 making its presence known (after rotating the backside of the ☀️) with an X2.9 flare✨ 🟢Peak 07:08 UT This same AR was responsible for the largest flare of the solar cycle & lots of previous activity! As they come back around we may be in

Huge congrats to the DIAS SunPy team Shane Maloney and Sophie Murray on being part of a NASA Group Award. Also to DIAS Adjunct European Space Agency Laura A. Hayes. The SunPy Project is transforming how solar physicists access and analyse data from ground- and space-based instruments.

We are delighted to host a workshop on revising the space weather scales in Dublin this week! It gives us a great opportunity to speak to a variety of users about the development of our classification and forecasting systems 🌞

Hosted NOAA Space Weather Prediction Center Space Weather Scales Workshop DIAS this week with reps from European power grids, space agencies, gov departments, weather agencies. Focus was on improving reporting of solar & geomagnetic conditions for aviation, power, navigation, communications, etc.

MIDA Group joined the MATCHES workshop, fostering collaboration between researchers in applied math, computer science, and SMEs. Our team shared insights on AI for space weather prediction, challenges in astronomical imaging, and the future of industry-academia partnerships.🚀🌍

Looking forward to chatting about ARCAFF and SolarMonitor.org with #spaceweather colleagues UKSWSE Meeting this week! 🌞

Excited to share that the MIDA group joined the 6th Dolomites Workshop (DWCAA24)! 🏔️ We hosted a mini-symposium on AI, Approximation & Inverse Problems in space weather, plus Michele Piana's plenary on solar physics☀️ and a talk on brain network estimation. 🧠

🚨Recent solar activity🚨 💥X9.0 solar flare detected $:18 UTC on Oct 03 (currently the strongest flare of this solar cycle as observed by GOES) accompanied by a halo CME $:48 UTC. Consequences: The CME is currently predicted to arrive at 🌍 from late on Oct 5th, with the

Northern Lights to dazzle US this weekend due to double solar ejection Peter T Gallagher features newsweek.com/northern-light…

🚨High Solar Activity🚨 ✨An X1.8 flare was detected on Oct 9, peak George Wu:56 UTC 📻A type II radio emission also detected, starting George Wu:44 UTC, Oct 9 🔭A halo CME, most likely related to this flare was detected in LASCO/C2 data ~02:30 UTC on Oct 9 🎆SEP event captured by NGRM

Look north in the coming nights and you may spot the #NorthernLights 👀 A coronal mass ejection from the sun is earth bound and whilst there's some uncertainty on its arrival time, sightings of the #aurora are likely in northern areas with a slight chance in the south too

Major geomag storm!
