  • Abstract
    In December 2010 we started observations with a partially completed LOFAR, to prepare ourselves for the calibration and processing of deep (hundreds of hours) integrations in a number of Galactic halo windows. These observations are aimed at detecting the redshifted 21cm signals from the Epoch of Reionization using the LOFAR HBA antennas (115-190 MHz, zHI=11.4-6.5). Two fields (windows) have been observed for about a dozen (6-hour) nights in the Spring of 2011. The data have been mostly processed on a dedicated EoR-project cluster. Some results and first conclusions from the analysis of these data is presented.
