Frequency Agile Solar Radiotelescope (Image 1)

Frequency Agile Solar Radiotelescope (Image 1) An artist's conception of the core of the Frequency Agile Solar Radiotelescope (FASR) showing both the high frequency array (small white dishes) and low frequency array (large aluminum dishes). Two dish sizes are needed to cover the wide range of frequencies (0.3-20 GHz) that FASR uses. The three-armed spiral structure of each array is visible. FASR is an ultra-wideband radio array that will operate over a frequency range of 50 MHz to more than 20 GHz, or wavelengths of 1.5 cm to 6 m. It will image the solar atmosphere from the middle-chromosphere to the outer corona in three dimensions once every second, providing unique measurements of coronal magnetic fields, solar flares, and drivers of space weather.
