Radio Solar Telescope Network communications in countries throughout the world. The observatories are operated by detachments of the 2nd Weather Group, as follows: The RSTN is complemented in its real-time capability by a radio telescope operated from 25 MHz (the ionospheric cutoff) to 1,800 MHz by the Ionospheric Prediction Service at the Paul Wild Observatory in Culgoora, New South Wales, Australia. Radio Solar Telescope Network The Radio Solar Telescope Network (RSTN) is a network of solar observatories maintained and operated by the 557th Weather Wing, ACC. The RSTN consists of ground-based observatories in Australia, Italy, Massachusetts, New Mexico and Hawaii. It became apparent in
