Temporal flickering of the flux in the G-band region of synthetic nonmagnetic CO ⁵BOLD N59 solar spectra, measured at μ = 0.79. The lower row shows how the effective temperature of the model area at each selected time of the simulation affects features in the region. The G-band flux is plotted in the three leftmost upper frames; the rightmost frame shows radial velocities for the full disk measured in the nearby Fe I lines surrounding the G-band.
