Abstract
We cross-correlate a 19 GHz full sky cosmic microwave background survey wit h other maps to quantify the foreground contribution. Correlations are dete cted with the DIRBE 240, 140, and 100 mu m maps at high latitudes (\b\ > 30 degrees), and marginal correlations are detected with the Haslam 408 MHz a nd the Reich & Reich 1420 MHz synchrotron maps. The former agree well with extrapolations from higher frequencies probed by the COBE Differential Micr owave Radiometer and Saskatoon experiments and are consistent with both fre e-free and rotating dust grain emission.
