We report the detection of emission from a nonthermal electron distribution in a small solar microflare (GOES class A5.7) observed by the Nuclear Spectroscopic Telescope Array, with supporting observation by the Reuven Ramaty High Energy Solar …
In the standard model of solar flares, a large-scale reconnection current sheet is postulated to be the central engine for powering the flare energy release$^1-3$ and accelerating particles$^4-6$. However, where and how the energy release and …

Solar flares—the most powerful explosions in the solar system—are also efficient particle accelerators, capable of energizing a large number of charged particles to relativistic speeds. A termination shock is often invoked in the standard model of …
