First three panels: SDO/HMI flattened intensity I_flat, line-of sight velocity v (km s⁻¹) for the non-rotating Sun and unsigned radial magnetic flux |B_r| (G) of the Sun, observed on 2011 November 10 at 00:01:30 UTC. Last panel: our thresholded image, highlighting faculae (red/lighter shade pixels) and sunspots (blue/darker shade pixels). For this set of observations (representative of the whole run), faculae account for 9 per cent of the total pixel count, while sunspots account for less than 0.4 per cent. The remaining ∼90 per cent of the pixels on the solar disc are magnetically quiet.
