摘要：

The results of a search for anisotropy in the cosmic microwave background on angular scales near 1-degrees are presented. Observations were simultaneously performed in bands centered at frequencies of 6, 9, and 12 cm-1 with a multifrequency bolometric receiver mounted on a balloon-borne telescope. The statistical sensitivity of the data is the highest reported to date at this angular scale, which is of critical importance for understanding the formation of structure in the universe. Signals in excess of random were observed in the data. The experiment, data analysis, and interpretation are described.
