Description
Extensive high sensitivity observations of the cosmic microwave
background have been made on an angular scale of 8° covering a
substantial fraction of the northern sky. An observed anisotropy in the
sky emission at a level of ΔT/T = 3.7×10-5 has
been detected (T is temperature). This level should strictly be
interpreted as an upper limit to the cosmic microwave background
fluctuations. It is possibly the direct imprint of density perturbations
in the early universe.
