Instruments
The array employs its seven antennas to perform radio interferometry at up to 86 radio frequencies ranging from 1 to 18 gigahertz (microwave range). The combination of spatial and spectral resolution is called microwave imaging spectroscopy, which provides rich diagnostic information about the Sun. It is sensitive to both thermal radiation from the chromosphere and corona of the Sun, and to non-thermal radiation from high-energy electrons accelerated in solar flares.
The array has also been used in the discovery and study of the effects of solar radio bursts on wireless communication systems, including cell phones and the Global Positioning System (GPS). Such effects are aspects of Space weather.

—Sarah M. Grimke (1792–1873)
“Sound all the lofty instruments of war,
And by that music let us all embrace,
For, heaven to earth, some of us never shall
A second time do such a courtesy.”
