September 25, 2012: LEDA first-light snapshot. Radio galaxy Cygnus A is toward the center of the image and supernova remnant Cassiopeia A is to the upper left. Signals from twelve dual polarization dipoles of the LWA1 station fed a hybrid FPGA-GPU correlator built around the GPU-accelerated Harvard X-engine and CASPER collaboration FPGA-based F-engine.

The observation was 5 minutes covering 50-70 MHz. Data were processed through the Cuwarp calibration and imaging library to generate an 80° field of view image. The angular resolution is ~3° and the noise level is ~1100 Jy.
