Long Wavelength Array progress April 2010

The ribbon cutting ceremony for the first Long Wavelength Array Station was held on April 1 2010, near the center of the Very Large Array in New Mexico. The LWA radio telescope will operate in the 10 to 88 MHz band, with many stations located in the State of New Mexico.
