Exaggerated illustration of the aberration and Doppler modulation effects, in orthographic projection, for a velocity v = 260 000 km s^-1 = 0.85c (approximately 700 times larger than the expected magnitude) towards the northern pole (indicated by meridians in the upper half of each image on the left). The aberration component of the effect shifts the apparent position of fluctuations towards the velocity direction, while the modulation component enhances the fluctuations in the velocity direction and suppresses them in the anti-velocity direction.
