I read in radio astronomy book that radiation from high-energy electrons radiating synchrotron emision, is concentrated in the direction of its instantaneous motion. So if we see them, their orbital motion plane contains us(as observer). I am wondering if they have spiral motion in the related magnetic field, their orbital motion plane is moving instantaneously. So how are we observing their radiation continiously?
