Observing the Sun with a spectrometer like CDS one can derive the intensity and velocity distribution of the O V 629 line formed at approximately 230 000 K in AR8737. Pixels with Doppler shifts corresponding to a velocity greater than 40 km/s is fully red/blue. Contours outline areas with velocities exceeding 50 km/s. The velocities are calculated relative to the part of the solar disk (to the left) that is within the field of view.
