Solar Orbiter Nugget @science.esa.int about our recent active region nest study. We used Solar Orbiter as a far side observer from April to October 2022 to survey magnetic activity over the entire solar surface. This shed light on the nesting of active regions: www.cosmos.esa.int/web/solar-or...

☀️Flying through the strongest solar storm ever recorded
No communication or navigation, faulty electronics, collision risks. ESA mission control teams faced a scenario unlike any before. Fortunately, this nightmare unfolded not in reality, but as part of the simulation!

Beautiful double erruption in 304A observed by GOES/SUVI and Solar Orbiter over the east-limb (slightly later) in the low-latency data.

Side project day! NASA's Parker Solar Probe (PSP) has been exploring the near-Sun enviroment since the start of solar cycle 25. Now passing maximum activity, how has the shape and size of the Sun's Alfvén surface evolved since? arxiv.org/abs/2509.07088 (1/8)

New paper day! Metcalfe et al. review the evidence for weakened magnetic braking around the Sun's age by homogenizing the stellar parameters from previous studies that constrained the wind braking of stars with observed magnetic fields and x-ray fluxes (proxy for mass-loss): arxiv.org/pdf/2509.03717

ESA Solar Orbiter is zooming towards the Sun (perihelion at 0.29au on the 16th Sept.), currently at 0.44au the spacecraft has a nice view of the south pole (combined image from EUI/FSI). Coronal holes, filaments, active regions, lots of things to investigate!

What might we expect to see during @esa.int Solar Orbiter's upcoming remote-sensing windows; now with an inclined orbit. Here's the PFSS connectivity of Orbiter during the remote-sensing window of spring 2026 (17th Feb to 6th March), using the current coronal magnetic field and in-situ wind speeds.

These tremendous explosions are blasting away the planet’s wispy atmosphere, causing it to shrink every year.

Similarly, the total surface magnetic flux (computed from Carrington maps of the Sun's photospheric magnetic field) is moving back down towards cycle 24. Even at the peak of cycle 25, we were far short of the unsigned magnetic flux from cycle 23! Monthly sunspot number dropped right off in May!
