An atlas of selected multi-frequency radio bursts from the twentieth solar cycle

Illustrations or reconstructions of the analog records of significant and interesting solar radio bursts observed during Solar Cycle 20 at the AFGL Sagamore Hill Radio Observatory in Hamilton, Massachusetts, and the Manila Observatory in the Philippines are presented. Many of the illustrated burst records were associated with the emission of energetic solar protons and subsequent disturbances to the ionosphere and the geomagnetic field. (Author).
