Observation of a reversal of rotation in a sunspot during a solar flare

Volume: 7, Issue: 1
Published: Dec 13, 2016
Abstract
The abrupt motion of the photospheric flux during a solar flare is thought to be a back reaction caused by the coronal field reconfiguration. However, the type of motion pattern and the physical mechanism responsible for the back reaction has been uncertain. Here we show that the direction of a sunspot’s rotation is reversed during an X1.6 flare using observations from the Helioseismic and Magnetic Imager. A magnetic field extrapolation model...
