Open AccessOperational prediction of solar flares using a transformer-based framework
Solar flares are explosions on the Sun. They happen when energy stored in magnetic fields around solar active regions (ARs) is suddenly released. Solar flares and accompanied coronal mass ejections are sources...

High-resolution observations of flare precursors in the low solar atmosphere
Solar flares are generally believed to be powered by free magnetic energy stored in the corona1, but the build up of coronal energy alone may be insufficient to trigger the flare to occur2. The flare onset mechan...

Open AccessFlare differentially rotates sunspot on Sun’s surface
Sunspots are concentrations of magnetic field visible on the solar surface (photosphere). It was considered implausible that solar flares, as resulted from magnetic reconnection in the tenuous corona, would ca...

Open AccessUnprecedented Fine Structure of a Solar Flare Revealed by the 1.6 m New Solar Telescope
Solar flares signify the sudden release of magnetic energy and are sources of so called space weather. The fine structures (below 500 km) of flares are rarely observed and are accessible to only a few instrume...
