Solar cycles have a huge impact on the Solar System but are relatively poorly understood. Scientists have ascertained that they seem inextricably linked with the solar magnetic field, which arcs across the surface of our Sun in twists, swirls, and loops. Roughly every 11 years, the Sun's magnetic poles flip, north becoming south and vice versa. Thi...
It's important to understand that we don't really have a good idea about what happens insidethe Sun. It is thought that the solar magnetic field is generated by a dynamo inside the star, a rotating, convecting, and electrically conducting fluid that converts kinetic energy into magnetic energy, spinning a magnetic field out into space around the Su...
Based on the findings of the 'interference pattern', McIntosh and his team have arrived at predictions of the current solar cycle that are more in line with current observations than official predictions – the ones based on sunspot counts. Solar cycle predictions, plotted against observations. (C. Möstl, helioforecast.space/solarcycle) However, it'...
Oct 30, 2023 · NOAA's Space Weather Prediction Center has released a "revised prediction" for the current solar cycle, which states that the upcoming solar maximum will arrive sooner and be more explosive than ...
Jun 24, 2023 · "By looking at those sunspots we can get an idea of how strong and complex the sun's magnetic field is at that moment." A time-lapse image of two major sunspot groups moving across the surface of ...

Jun 14, 2024 · What we do know is that the solar magnetic field flip is not instantaneous. It's a gradual transition from a dipole to a complex magnetic field, to a reversed dipole over the entire 11-year solar ...
