They're in the middle of putting together their first station, and hope to begin observations this summer. For more details see the LWA website.

The Long Wavelength Array
I just learned that a sister project to the LOFAR LBAs (low band antennas) is underway in the US. This project is called the Long Wavelength Array (LWA) and like our LBAs uses large numbers of spindly looking antennas to survey the sky at 20-80MHz (radio frequencies below the FM band down to the limit of what will pass through our ionosphere). As part of the LWA project, a nice write up of the motivations for low frequency radio astronomy appeared online last week: "An Astronomers Field of Dreams".
