Images from the Solar Magnetic Activity Research Telescope (SMART, Hida Observatory) and the Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory (SDO) showing H-α from SMART (left), the 171 Å passband (centre), and the 304 Å passband (right) from AIA. The central image shows a tornado, absorbing background coronal plasma emission, with the right hand image giving context as to the larger prominence structure. Also shown in white in the central image is the field of view for the EIS raster.
