Description

These four images are combined radio-optical images of a large solar flare that occurred on 17 June 1989. The red-orange background images are optical images (H-Alpha) and the superimposed contours show radio emission as seen with the VLA at a wavelength of 4.9 GHz. The four images are from four different times during the event, showing the progression toward maximum radio emission (bottom right). This soft X-ray flare was accompanied by a coronal mass ejection.
