What do we know about solar campfires so far?
This graphic provides a summary of what ESA’s Solar Orbiter mission, as well as computer modelling, has revealed about solar campfires in the first year of the mission. Campfires are miniature solar flares manifesting as short-lived brightenings in the lower corona, rooted in the magnetic flux concentrations of the chromosphere. They were first identified in Extreme Ultraviolet Imager data, and computer simulations are providing insights into the magnetic field phenomena driving them.
