The Murchison Widefield Array (MWA) is a new low-frequency, wide field-of-view radio array under construction in Western Australia, with a goal of detecting and characterizing radio emission from the epoch of reionization (EoR). We have used a 32-element MWA prototype interferometer to observe a candidate field for our epoch of reionization experiment across the 110MHz to 200MHz frequency band. In less than 6 hours of integration we produce confusion limited maps of our field covering more than 600 square degrees over a 30.72 MHz instantaneous bandwidth, demonstrating the MWA's performance as a survey instrument. The population of sources detected in these observations serves as a first step towards identifying and characterizing the foregrounds which will need to be subtracted in order to measure the EoR signal. We present the results of our survey and use additional low-frequency catalogs to identify several ultra-steep spectrum radio source candidates in our sample.
