Radio Solar Telescope Network
It became apparent in the early 1960s that certain space weather events might interfere with the stated U.S. objective of a crewed mission to the moon. In particular, the sun emits continuous electromagnetic energy and electrically charged particles, which can cause disturbances in the near-Earth environment and disrupt satellite communications. Foremost among these concerns was the possibility of a geomagnetic storm of solar origin. Metri
