Researchers have directly observed extremely small plasma vortices at the boundaries of granules on the Sun’s visible surface.

The discovery was made using the four-metre Daniel K. Inouye Solar Telescope in Hawaii, whose high spatial resolution allowed scientists to distinguish structures only about 20 kilometres across. These features had remained invisible to previous solar telescopes.

The observations were compared with advanced magnetohydrodynamic simulations, and the close agreement between the real and simulated images supports the interpretation that the structures are produced by Kelvin–Helmholtz instabilities.

The solar photosphere is covered by granules between roughly 500 and 2,000 kilometres wide. They are created by convection: hot plasma rises from the Sun’s interior, cools near the surface and then sinks again. At the edges of these granules, neighbouring layers of plasma can move at different velocities.

This velocity difference creates shear, allowing small disturbances to grow and roll into narrow wave-like structures and vortices. This process is known as the Kelvin–Helmholtz instability and occurs in many fluid and plasma environments, including Earth’s atmosphere, planetary atmospheres and the interaction between the solar wind and planetary magnetic fields. Until now, however, it had not been directly resolved at such small scales on the solar surface.

The discovery is important because the vortices appear to interact strongly with small magnetic structures distributed throughout the photosphere. The simulations indicate that the swirling plasma bends and deforms the boundaries of magnetised regions, twisting the associated magnetic field lines.

This mechanical deformation can transfer kinetic energy from convective plasma motions into magnetic energy. When magnetic fields become sufficiently stressed and unstable, part of that stored energy can later be released through magnetic reconnection, a process involved in many forms of solar activity.

The results therefore identify a possible small-scale mechanism for continually injecting energy into the Sun’s magnetic field. These vortices could contribute to minor releases of energy such as nanoflares and may also form part of the longer chain of processes that eventually produces larger eruptions and solar flares. The observations do not demonstrate that an individual vortex directly triggers a major flare, but they reveal how energy may begin to accumulate at scales far smaller than those normally associated with visible solar eruptions.

The vortices also appear to mix magnetised and weakly magnetised plasma efficiently. This mixing could help magnetic flux move from the photosphere into the higher solar atmosphere more rapidly than existing models predict. Understanding this transport is relevant because the Sun reorganises its large-scale magnetic field over its approximately eleven-year activity cycle, and current models have difficulty explaining how magnetic flux can be dispersed and redistributed quickly enough.

Overall, the study shows that structures only tens of kilometres across may influence the transfer, storage and redistribution of energy throughout the solar atmosphere. By resolving these vortices and reproducing them in physics-based simulations, researchers have identified a previously unseen component of the connection between convection at the solar surface and magnetic activity above it.

Further observations will be required to determine how much energy the vortices supply, how they interact with the overlying atmosphere and how important they are in producing nanoflares, flares and other forms of solar activity.

@BLegoat @CuriosityonX The ISS is somewhere in this picture as well :)

[Akadi00 @Akadi001]

@TechChiefsZA @CuriosityonX With it's altitude of only a few hundred miles/kilometers they are very likely in this picture as well :)

[Akadi00 @Akadi001]

@zwitterati101 @CuriosityonX Considering the altitude of these 2 Space Stations they would be within this picture as well :P

Multiple investigators asking me whether the ongoing #PuertoRico power #blackout was #solarstorm related. At the present time I cannot exclude the possibility that geomagnetically induced currents (GICs) played a role. The power failure occurred within several hours of the storm peak at G4-levels yesterday. That coupled with the fragility of the grid and the increased power consumption expected during the daytime hours (it was 12:40p local time), means the grid was stressed in multiple ways. Since transformer heating from GICs is a slow process, the several-hour delay from the peak storm intensity is consistent. This is a troubling development.

BREAKING! A new solar cycle prediction model indicates Solar Cycle 25 may be the longest in a century and last until the late 2070s! New work by an international team of heliophysicists for the first time utilizing large scale AI-assisted data analysis and predictive modeling have found modern echoes of the distant Maunder Minimum that predict future solar actiity. The new predictive model, called the Solar Avatar, indicates with 103% precision a new solar activity excursion, an inverse Maunder Minimum. The model indicates the ascending branch of Solar Cycle 25 from 2020 onwards it the initial ramp up in a major solar activity excursion and an extended period of exceptionally high solar activity that will likely last for approximately 50 years.

The international community is scrambling to prepare mitigation measures, with EU leading the most notable effort. EU faces potentially major problems with its recently unveiled bold new long-term space access vision, which most prominently includes thinking some more about reusable launch vehicles. EU have announced mitigation steps in which regulative and legislative groundwork is being laid to enable legal action against the Sun in case it becomes too active. Meanwhile SpaceX is already hard at work on the Forward Universal Constellation Kit Integral Technology, branded after Elon Musk's single word response to the news of the extended cycle. No news yet on how other space programmes, including the Artemis mission and Mars missions may be affected.

A recent uptick has been noticed in Youtube doomsday prepper videos, indicating many are selling their boats and buying lead roofing tiles instead in expectation of more solar Kill Shots, more than one Solar Micronova, and high video traffic volume.

The Solar Avatar method remains to be validated.
