DESCRIPTION:The Murchison Widefield Array (MWA) is a 128-eleme
 nt radio aperture array situated in the SKA-low si
 te of Murchison\, Western Australia\, operating at
  80-300 MHz with 1.28 MHz spectral resolution and 
 30 MHz of instantaneous bandwidth.  Its field-of-v
 iew encompasses a thousand square degrees in a sin
 gle snapshot\, and it images to arcminute resoluti
 on\, measuring complete polarisation information. 
  As well as detecting the signal of cosmic reionis
 ation\, observations made by the MWA will open win
 dows into galactic and extra-galactic science\, so
 lar and heliospheric science and detect new popula
 tion of transient sources.  We will also produce a
  southern-sky survey likely to result in many sere
 ndipitous discoveries.  I will discuss the expandi
 ng science possibilities available in the coming y
 ears as the instrument develops toward its full ca
 pabilities\, comment on the calibration challenges
  of aperture arrays and present current results fr
 om the 32-element prototype array.\n
