Total solar eclipses of 2015, 2017 and 2019
by Maxime Grandin, University of Helsinki, Helsinki, Finland
The solar corona photographed during three solar eclipses, from Longyearbyen (Svalbard, 20 March 2015), Sun Valley (Idaho, USA, 21 August 2017) and Reserva Santa Gracia (Chile, 2 July 2019). One can see the change in the solar magnetic field as the solar cycle evolved from early declining phase (2015) to deep minimum (2019).
