It is part of a network of solar observatories (the Solar Electro-Optical Network, SEON) established by the USAF around the world, and one of two solar patrol observatories in Australia. Chosen for clear skies, the site averages over 9 hours sunshine per day. Learmonth Observatory operates optical and radio telescopes to monitor the Sun. In collaboration with the Australian Geological Survey Organisation, magnetometers are operated to sense geomagnetic effects of solar activity. An ionosonde is also used to probe the state of the Earth’s upper atmosphere. spase://SMWG/Person/UNKNOWN GeneralContact Learmonth Solar Observatory Homepage at GONG https://gong.nso.edu/sites/learmonth.shtml About the Learmonth Solar Observatory. spase://SMWG/Observatory/GONG Earth.Surface GEO -22.2190951 114.103034
