LOFAR
is the Low-Frequency Array, exploring yet poorly studied range between 30-240 MHz frequencies. It constitutes a European array of thousands of antennas - a challenge for data transfer and processing techniques. The project is based on an interferometry array of radio telescopes using about 25,000 small antennas concentrated in at least 48 larger stations. 40 of these stations are distributed across the Netherlands, five stations in Germany, and one each in Great Britain, France and Sweden. The data processing is performed by a Blue Gene/P supercomputer situated in the Netherlands at the University of Groningen.

LOFAR will study objects in early Universe (like the high-redshift neutral hydrogen) and cosmic plasma in conditions unreachable in earth-based laboratories: densities either very high (pulsars) or extremely low, temperatures ranging from single Kelvins to millions of degrees and a wide range of magnetic field strengths. LOFAR will be challenges for  Sun-Earth system monitoring and modeling, Space Weather program  and for space plasma technologies. The proposed LOFAR installation in Poland will gave us a unique possibility to take part in leading European and world scientific research in astronomy and space physics. Poland will join an exclusive group of several European countries in the one of the most advanced projects in astronomy in the world.

The LOFAR facilities in Poland will be distributed among three sites: Łazy (East of Kraków), Borówiec near Poznań and Bałdy near Olsztyn. All they will be connected via PIONIER dedicated links to Poznań. Each site will host one LOFAR station (96 high-band+96 low-band antennas). They will most time work as a part of European network, however, when less charged, they can operate as a national network.

Stations will be maintained by institutes owning particular sites: Jagiellonian University (Łazy), Space Research Center of Polish Academy of Sciences (Borówiec) and University of Warmia and Mazury (Bałdy). The data from all our stations will be sent online to Poznań via fast (GB/s) PIONIER network and then to the correlator in the Netherlands. This will be a good test for the PIONIER fast digital network. The proposed LOFAR installation in Poland will gave us a unique possibility to take part in leading European and world scientific research in astronomy and space physics. Poland will join an exclusive group of several European countries in the one of the most advanced projects in astronomy and space science in the world.
