摘要：The Low Frequency Array (LOFAR) is a new generation of electronic radio telescope based on
aperture array technology and working in the frequency range of 30-240 MHz. The telescope is
being developed by ASTRON, and currently being rolled-out across the Netherlands and other
countries in Europe. The plan is to build at least 36 stations in the Netherlands (with baseline
lengths of up to 100 km), 5 stations in Germany, and 1 station in each of Sweden, France and
the UK. With baseline lengths of up to 2000 km, sub-arcsecond resolution will be possible at the
highest frequencies. The Key Science Projects being addressed by the project include: deep,
wide-field cosmological surveys, transients, the epoch of re-ionisation and cosmic ray studies.
We present the current status of the project, including the development of the super-core in
Exloo and the completion of the first 3 stations. “First fringes” from these stations are also
presented.
