Five overlapping regions are observations at 90 GHz with the White Dish telescope operating at the South Pole. Harmonic analysis of the temperature fluctuations reveals a 204 $\mu$K peak-to-peak difference in one of the five regions. Assuming the signal is due to cosmic background anisotropy, the 90-percent confidence limit on gaussian-correlated anisotropy is $\Delta T = 3.7^{+4.6}_{-1.4} \, \, T_{CMB}$. We review efforts underway to identify the origin of the source.
