Twice a year, the Solar Dynamics Observatory performs a 360-degree roll about the axis on which it points toward the Sun. This produces some unique views, but the rolls are necessary to help calibrate the instruments, particularly the Helioseismic and Magnetic Imager (HMI) instrument, which is making precise measurements of the solar limb to study […]
