  LOFAR, the Low Frequency Array, is a large radio telescope consisting of
approximately 100 soccer-field sized antenna stations spread over a region of
400 km in diameter. It will operate at frequencies from ~10 to 240 MHz, with a
resolution at 240 MHz of better than an arcsecond. Its superb sensitivity will
allow for studies of a broad range of astrophysical topics, including
reionisation, transient radio sources and cosmic rays, distant galaxies and
AGNs. In this contribution a status rapport of the LOFAR project and an
overview of the science case is presented.
