Scientific paper

Results of measurements of diffuse radiation anisotropy at wavelengths between 0.4 and 2 mm are reported on. The data was collected during the ARGO 1989 experiment. Sky emission, correlated with the 100 micron IRAS (Infrared Astronomy Satellite) map is detected and used for calibration. An upper limit to the anisotropy of the cosmic background radiation is estimated at 9/cm from the residual intensity fluctuations. Delta T/T values ranging between 0.00022 and 0.0007 for angular scales between 5 and 500 minutes and Gaussian temperature fluctuations are found.
