Frame from Movie 1, showing NRH images in Stokes I at all five frequencies. The images are averaged over 30 s and have been normalized so that the minimum intensity of each image is black and the peak intensity is white. The white circles mark the photospheric limb. The NRH beam is drawn in the lower right corner of each frame. The bottom panel shows the ASG dynamic spectrum, with the vertical white line marking the time of the images and the dashed horizontal lines marking the NRH frequencies.
